What Is Aluminum Strip Width

 At present, the width of aluminum coils is generally between 800-2600mm. The commonly used width is within 1000-1500mm. Within this width, the price is more appropriate and cost-effective. The wider the width, the higher the price.

The width of the aluminum coil is related to the rolling equipment and the flattening equipment. The higher the width, the higher the pressure required by the equipment and the higher the equipment cost. Therefore, there are not so many manufacturers of ultra-wide aluminum coils.

The thin aluminum strip is a product made of aluminum coil processed by a slitting unit. The width is usually between 10mm-900mm. Usually the width of the aluminum strip is relatively narrow. It is often used in hardware and lamp stamping, transformers and related electronic appliances and cable armoring. The aluminum strip 15mm is a popular choice.

Technical advantages of aluminum coil slitting and straightening

Its main advantages are reflected in its accuracy, stability and efficiency. It has high precision and can achieve precise slitting and straightening of aluminum coil. It has strong stability and the straightening accuracy can be continuously maintained; it is also very efficient and can split tens of meters of aluminum plates at a time, which greatly improves the production efficiency of the factory.

The aluminum coil slitting and straightening process

Firstly, the aluminum coil is put into the slitting machine, and then the aluminum coil is transferred to the straightening machine. In the straightening machine, the aluminum coil will be rolled to the required width and can be accurately straightened.

Then, put the straightened aluminum coil into the slitting machine, and adjust the parameters of the slitting machine to realize the slitting of the aluminum plate and complete the entire aluminum coil slitting and straightening process.

Aluminum coil slitting and straightening technology is widely used in industrial fields, especially in the home appliance industry. In the home appliance industry, aluminum coil slitting and straightening technology can accurately divide thick aluminum coils into precise aluminum plates, and can be accurately straightened to ensure the overall appearance and performance of home appliances. The aluminium strip 25mm x 3mm is often used.

During the implementation of the aluminum coil slitting and straightening technology, certain requirements need to be met, including the type and thickness of the aluminum coil, as well as the quality and size of the aluminum coil. If the type of aluminum coil, aluminum strip thickness and quality do not meet the requirements, it will affect the effect.

Aluminum Foil: An Indispensable Part of Flexible Packaging

 Aluminum foil packaging makes it more convenient to pack food in the right amount. Therefore, food can be prepared and consumed as needed, thus reducing waste. At the same time, it also ensures the nutritional content and health needs of the product. Smaller packaging prevents product damage and wastage compared to larger packaging, thus saving resources overall.

However, in food packaging, aluminum foil is rarely used alone because aluminum foil itself has some shortcomings. For example, as aluminum foil is further thinned, the number of pores will increase, which will affect the barrier properties of the flexible packaging foil. sually, aluminum foil can be combined with other packaging materials to make composite packaging materials to make up for the shortcomings of aluminum foil, thereby improving the comprehensive packaging performance of composite packaging materials.

Aluminum foil is an important component of flexible packaging materials. Aluminum foil can block light, oxygen, moisture and bacteria, so it is widely used in food and pharmaceutical packaging. Aluminum foil can also play a role in beautifying products and improving product quality. Aluminum foil flexible packaging is mainly used for food bags, beverages, candy, chocolate, and cooked food. The thickness of aluminum foil used in flexible packaging is usually between 7 and 9 micron.

8079 and 1235 aluminum foil both have a wide application in flexible packaging. Due to their excellent characteristics, they both have a certain status in flexible packaging. 8079 aluminum foil is widely used in food and drug packaging, electronic and electrical appliance packaging and household daily necessities. The aluminum content of 1235 aluminum foil is more than 99.35%. It is also a kind of pure aluminum foil and is widely used in cables, tapes, and battery foils.

The surface of food grade aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material that can be in direct contact with food without any danger to human health. Haomei food aluminum foil has undergone multiple tests for bacteria, mold, etc., and the heavy metal does not exceed 0.25 parts per million.

6101 and 6111 Aluminum Sheet for Car Making

 Alloy 6101 is often used to process high-strength bus conductors. When the aging system is (200±5)℃×5 h, the conductivity of 6101 aluminum is greater than 55%IACS, the tensile strength can reach 172-221 MPa, and the yield strength can also reach 138-186 MPa.

Aluminum-magnesium-silicon alloys are the most widely used aluminum alloys in wires and cables. They are 6101 and 6201 alloys, and the tempers are T1 and T4. In 2020, the consumption of this aluminum alloy in the world will exceed 5000kt, and the consumption in China is expected to exceed 1600kt, accounting for more than 30% of the total consumption.

The standard electrode potential of aluminum is -1.662V, and the electrochemical equivalent is 0.3356g/(A·h). The density of aluminum is only 30.13% of that of copper. Therefore, replacing copper with aluminum can significantly reduce the quality of workpieces, thereby saving energy and reducing greenhouse gas emissions.

After introducing pre-strain and pre-aging on the basis of artificial aging, the mechanical properties and electrical conductivity of 6101 aluminum alloy are improved. When the solid solution alloy was deformed by 60% cold rolling and aged at 180°C for 6 h, the yield strength, tensile strength and electrical conductivity of the alloy were 249 MPa, 262 MPa and 55.7% IACS, respectively, which are higher than the alloys hat reach their peak-aged state after conventional artificial aging.

6000 series aluminum alloys have received more and more attention as the as car exterior body panels because of their good comprehensive properties. Usually, the main production and processing steps of 6xxx series aluminum alloy sheets are: ingot casting-hot rolling-annealing-cold rolling-solution treatment.

Among the registered 6xxx series automobile body plate alloys, the 6111 aluminum sheet has both high strength and good formability, and has become one of the aluminum alloys that have been widely concerned and researched at home and abroad.

When the aging temperature is 165 degrees Celsius, the time to reach the peak strength is the longest, which is 15 h, but the peak strength and elongation are the highest. The yield strength is 343 MPa, the tensile strength is 392 MPa, and the elongation is 18.1%.

When the aging temperature is 185 °C, it is just the opposite, and 175 °C is in the middle; the hardness and strength of the alloy are positively correlated, and the hardness reaches the peak at 165 °C x15h, which is 133.5 HV.

Marine Grade Aluminum 5086 5456

 Marine grade aluminum 5086 is an aluminum-magnesium alloy. It is strengthened not by heat treatment, but by strain hardening or cold working of the material. 5086 alloy is easily welded and retains most of its mechanical strength. 5086 aluminum s the recommended hull material for small aluminum boats and larger yachts. Its high strength and excellent corrosion resistance make it ideal for yachts. 5086 h116 aluminum is a popular choice.

A tugboat refers to a ship used to tow barges and ships. It has firm structure, good stability, small hull, large main engine power, large traction force and good maneuverability. Tugboats can also be made of aluminum alloy. The hull of the American "Sauter" tugboat is welded with 5083 and 5086 alloys, and the manufacturing time is about 30% shorter than that of steel barges.

Al-Mg alloys are used in many countries as hull structural materials. From 1966 to 1971, the United States built 14 "Ashville" class high-speed gunboats. The main deck and bottom plate were made of 12.7mm thick 5086-H32 aluminum alloy, and the profiles were made of 5086-H112 aluminum alloy.

The United States mainly uses 5456 aluminum alloy plate. The Mg content of 5456 alloy is 5 wt%, which is much higher than 3 wt%. This corrosion-sensitive alloy is susceptible to stress corrosion both in plate fabrication and in service. Sensitive stress corrosion can only occur under the combined action of three factors: organizational structure, corrosive medium, and stress.

The marine grade aluminum 5456 can adapt to the long-term humid marine environment, has good corrosion resistance, vibration resistance, and excellent low temperature performance, and the price of the 5456 aluminum plate is relatively reasonable, and the shipbuilding cost is low. 5456 aluminum alloy plate is widely used in shipbuilding, which shows its excellent characteristics.

In shorter aging time, the weight loss of 5456-H116 alloy is almost twice that of 5083-H116 alloy. When the aging time exceeds 150 h, the weight loss of the 5083-H116 alloy is much higher than that of the 5456-H116 alloy, indicating that after the aging time is >100 h, the corrosion sensitivity of the 5456 alloy is much lower than that of the 5083-H116 alloy.

5454 Al-Mg alloy is a wrought alloy with medium to high strength and excellent weldability. Its strength is approximately the same as that of 5154 and about 20% greater than that of 5052. 5454 aluminum is commonly used in welded structures such as pressure vessels and ships.

Alloy 5454 was used in tank trucks in the early 1950s, and it has good anti-corrosion properties. In addition, 5454 plates can be used in high-temperature environments, or transport high-temperature liquids. 5454 h32 aluminum is a popular choice.

5454 aluminum alloy plate production process: cold rolling processing rate of more than 70%. The annealing temperatures for states 0, H22, H24, H26, and H28 are 300°C, 260°C, 250°C, 230°C, and 200°C, respectively, and the holding time is 1 hour. The 5454 alloy H2n and O state plates produced by this process have stable properties and good formability, which meet the requirements of the EN485 standard.

5754 aluminum sheet has the characteristics of medium strength, good welding performance and excellent processing and forming performance. 5754 aluminum coil can be used to manufacture tank car bodies and bulkheads, which can reduce the weight of tank cars, increase the load, reduce fuel consumption and reduce exhaust emissions.

Moreover, the 5754 aluminum plate has strong corrosion resistance and can greatly prolong the service life of the tank car. Therefore, it is favored by the tanker truck making industry and has become the designated aluminum plate for many tank car manufacturers.

The magnesium content of 5754 aluminum sheet is higher than that of 5052, so the machinability is better. The silicon content of 5754 aluminum plate is also more than that of 5052. The silicon content affects the forging function and corrosion resistance of aluminum alloy, so 5754 aluminum plate has better forging functionality and corrosion resistance.

7000 Aluminum: Aluminum 7075 Alloy

7000 aluminum is a high-quality, high-strength aluminum alloy that is widely used in aviation, automobiles, machinery manufacturing and other fields. Its typical grade is 7075 aluminum plate that mainly contains zinc elements. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy.

7000 aluminum alloy has high strength and hardness, and its tensile strength and yield strength are higher than other series of aluminum alloys. This high strength and hardness make the 7000 series aluminum alloy perform well when withstanding high loads and impacts, and can meet the needs of various complex application scenarios.

7000 series aluminum alloy has excellent welding performance and can be welded by various welding methods such as argon arc welding and gas shielded welding. During the welding process, the 7000 series aluminum alloy has a low melting point and is easy to perform welding operations. At the same time, its welded joints have high strength.

7000 aluminum alloys have good corrosion resistance and can resist corrosion from environmental factors such as atmosphere, seawater, acid and alkali solutions. In complex industrial environments, 7000 series aluminum alloy can effectively protect parts from corrosion damage and extend the service life of equipment.

7000 aluminum alloys have good processing properties and can be used for various mechanical processing operations such as milling, drilling, planing, and grinding. At the same time, the heat treatment performance of 7000 series aluminum alloy is also good, and its strength and other mechanical properties can be further improved through heat treatment.

Zinc is the main alloy element in the aluminum 7075 alloy . Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the alloy's heat treatment effect far better than that of aluminum-zinc binary alloy. Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and spalling corrosion will decrease.

After heat treatment, 7075 aluminum can achieve very high strength properties. 7075 aluminum sheet generally adds a small amount of copper, chromium and other alloys. Among this series, 7075-T651 alloy is particularly top-grade and is known as the best product among aluminum alloys. It is widely used in the aerospace, mold processing, mechanical equipment, and tooling fixtures. It is especially used to manufacture aircraft structures and high-stress structures that require high strength and strong corrosion resistance.

What Is Aluminum Used for in Cars

 Compared with other lightweight materials like high-strength steel, magnesium alloy and carbon fiber, aluminum alloy is slightly higher than that of high-strength steel, and much lower than that of magnesium alloy and carbon fiber materials.

The density of aluminum alloy is 2.8g/cm3, and the weight reduction rate is between 40% and 50%, which is only weaker than carbon fiber and magnesium alloy, and significantly stronger than high-strength steel.

Aluminum alloy has the highest recycling rate, and its wide application can promote the development of the recycled aluminum industry, which meets the current urgent needs for energy conservation and emission reduction, and can also further reduce the cost of upstream raw materials. Based on the above advantages such as high specific strength, high weight reduction rate, and excellent anti-corrosion performance, the use of aluminum alloy is increasing year by year.

Deformed aluminum alloy is a kind of aluminum alloy and one of the light metal materials with great development potential. It is widely used in construction, machinery, electronics, packaging, automobiles, ships, rail transportation, aerospace and other fields. Among them, automobiles are the main application field of deformed aluminum alloys.

Deformed aluminum alloys are mainly used in the manufacturing of automobile body parts such as doors, fenders, trunk lids, outer covers, and engine hoods. 5754 aluminum alloy is used in the manufacturing of door linings. It has the advantages of high strength, good plasticity, high specific strength, good welding performance, strong temperature resistance, good corrosion resistance, and high fatigue resistance. 5754-h111 aluminum is one of its main tempers.

The 6000 series aluminum alloy is a heat-treatable strengthened alloy, with Mg and Si as its main alloy elements. It is usually used for automotive exterior panels that require high stiffness and strength. 6061 aluminum is one of the main 6000 aluminum alloys. Al6061 t6 is a common temper.

It can be seen from the stress-strain curves of the two types of aluminum alloys that 5754 aluminum alloy is only suitable for manufacturing inner panels of automobile bodies, while 6061 aluminum alloy is more suitable for outer covering parts in automobiles that require high surface quality.

The fracture mode of 6061 aluminum alloy is similar to that of 5754 aluminum alloy. They are both ductile fractures. However, the number of dimples in the fracture of 5754 aluminum alloy is larger, and the depth of the dimples is deeper than that of the 6061 aluminum alloy.

The metallographic structure shows that the grains of both 5754 aluminum alloy and 6061 aluminum alloy elongate after deep drawing fracture. A small amount of creep cracks appear between grains in 5754 aluminum alloy; while there are obvious cracks both within and between grains in 6061 aluminum alloy.

What Are The Development Trends of Fishing Boat Hull Materials

 From the perspective of material recyclability, steel, aluminum alloy, and polyethylene are selected to build fishing boats. The common grades of marine aluminum plated are 5083, 5052, 5086, 6061, 6082 aluminum sheet. The hull materials that have reached the end of life can be recycled, reprocessed, and reused, which meets the requirements for effective use of natural resources.

However, steel has poor resistance to environmental corrosion and has a rough surface, which is easily adhered to by aquatic organisms. A large amount of steel is lost due to corrosion every year. Therefore, the surface of steel used in ship construction must be sprayed with paint, and paint can cause water pollution and poison aquatic organisms.

Although fiberglass fishing boats have very obvious advantages over traditional wooden fishing boats in many aspects, their scrapped hull materials cannot be recycled and pollute the environment. It can be seen that aluminum alloy and polyethylene are sustainable fishing boat construction materials.

Development Trend of Fishing Boat Hull Materials

Energy-saving materials

As people's awareness of the energy crisis and environmental protection increases, the requirements for energy conservation and emission reduction of fishing boats are getting higher and higher. At present, fiberglass composite materials, high-density polyethylene materials, and aluminum alloy materials are the primary choices for building fishing boats.

High strength material

As the offshore fishery resources in various countries around the world become increasingly tight, the competition to obtain distant-water fishery resources becomes more and more fierce. Distant-water fishing boats are gradually developing towards large-scale and multi-functional. Fishing boats operating in the open sea for a long time need to cope with various harsh meteorological environments, which has a negative impact on the hull strength of fishing boats. There are very high requirements for the strength of fishing boat hulls.

Corrosion-resistant materials

Ships have been in the marine environment for a long time, and the problem of hull corrosion has always been the focus of people's attention. Reasonable anti-corrosion design is a key factor in controlling ship corrosion. The selection of construction materials, the design of ship structure and the ship construction process all have certain effect on the corrosion resistance of the hulls.

Low cost material

At present, the hull construction cost accounts for more than half of the total cost, which mainly includes material procurement fees and labor fees. The difficulty of material processing determines the construction cycle, which in turn affects labor costs. Therefore, materials that are cheap and easy to process and form, such as composite masking materials are much favored.
