Super Hard 2024 Aluminum Strip

 What is 2024 aluminum alloy

2024 aluminum alloy is a kind of high-strength duraluminum, which belongs to the Al-Cu-Mg series. It is mainly used to make various high-load parts and components. It can be strengthened by heat treatment and has medium plasticity in the quenched and just-quenched state. The corrosion resistance is not high, and anodizing treatment and painting methods are often used to improve its corrosion resistance.

It is mainly used to make various high-load parts and components (but not including stamping forgings), such as air frame, skin, ribs, spars, rivets and other working parts below 150 °C on aircraft.

Typical Aircraft Aluminum Sheet 2024

 High-strength aircraft aluminum sheets are of low density, high strength, and good thermal processing performance, which have broad application prospects in aerospace components. For example, high-strength aluminum alloy thick plates are used as the main load-bearing components, and the proportion of use accounts for 30% to 35% of the total aluminum consumption in the aircraft.

Aluminum-copper (2000 series) alloys are the predominant aluminum alloys used in airframe structures, where the primary design criterion is damage tolerance. Compared with other series of aluminum alloys, 2000 Al-Cu alloys have higher strength, higher damage tolerance and good fatigue crack growth resistance due to the precipitation of Al2Cu and Al2CuMg phases. 2024 are the typical grade.

2024 aluminum is a typical hard aluminum alloy with good comprehensive performance. It has high compressive strength, certain temperature resistance, and can be used as working parts below 150 degrees. After heat treatment, the 2024 aluminum alloy has undergone solid solution treatment to obtain relatively high compressive strength and ductility. It is generally used to produce skins, roof beams, bulkheads, and wings of airplanes.

The compressive strength of 2024 aluminum sheet is higher than that of 7075 aluminum sheet. The forming properties are better in the thermal condition, quenching and new heat treatment conditions, and the heat treatment process enhancement effect is remarkable, but the heat treatment method is strictly specified. Its corrosion resistance is weak, but it can be reasonably maintained by cladding with pure aluminum.

2024-T3 is one of the most widely used alloys in airframe construction. It has moderate yield strength, very good resistance to fatigue crack growth and good fracture toughness. 2024 aluminum sheet remains an important aircraft structural material due to its excellent damage tolerance and high resistance to fatigue crack growth under T3 aging conditions.

6016 Automotive Aluminum Sheet

 The automotive aluminum sheets can be classified into 5000 series, 6000 series and 7000 series in terms of alloy composition. 5754, 5182, 5023 are used for inner covering parts and structural parts; 6016 aluminum, 6014, 6022, 6111 are used for outer covering parts.

6000 aluminum alloys are currently the most widely used aluminum alloys for automobile sheet metal parts in the automobile industry. They have excellent formability, high strength performance, corrosion resistance, hemming performance, high surface performance, etc. At the same time, after painting and baking, the strength performance has been improved to a certain extent.

6009, 6010 and 6016 aluminum alloys are currently used in the outer and inner panels of automobile bodies due to their good plasticity and the artificial aging that can be achieved in the process of painting and baking after forming to obtain higher strength.

6016 aluminum sheet is used in the outer panel of the car door, which can meet the dent resistance design requirements by increasing the thickness of the sheet and optimizing the structure. Under the premise of meeting the rigidity, strength design requirements and relevant collision regulations, AA6016 aluminum alloy plates can be widely used to replace traditional steel plates in the outer panels of automobile doors, so that the weight can be reduced by more than 40%, and the purpose of lightweight can be achieved.

The 6061 alloy reaches medium strength after special treatment (T6), and its strength is higher than that of the 5 series alloys. Moderate strength is very suitable for the automotive industry. The aluminum alloy sheet used for different parts of the automobile body is also different. Among them, the 6061 aluminum sheet is used for the car fender, outer hood panel and car door.

The 6016 aluminum sheet can meet the vehicle manufacturing requirements after the solid solution-T4P-baking paint treatment, but the process parameters have a great influence on the final performance.

Insufficient solution treatment reduces the precipitation power of T4P and artificial aging during the baking process. Long holding time may lead to grain coarsening. Low pre-aging humidity will reduce the performance stability of the plate during placement and the hardening effect during the baking process.

If the temperature is too high, it will affect the formability of the stamping process. It can be seen that the solid solution and T4P process parameters should be optimized in order to obtain ideal comprehensive properties.

5356 Filler Rod Aluminum Wire Price

 The most widely used aluminum welding wires for welding are 4043 and er5356.

SAL4043, commonly known as ALSil, is an aluminum filler metal containing 5 percent silicon and can be recommended for welding 3003, 3004, 5052, 6061, 6063 and casting metals 355, 356 and 214. The melting point temperature range of ER4043 is 1065-1170oF, the color after anodizing is off-white, and the tensile strength is as low as 186MP.

Performance characteristics: It is a kind of aluminum-silicon alloy welding wire with great versatility. The weld metal has excellent thermal crack resistance and can also guarantee certain mechanical properties. However, in the case of anodizing treatment, the color of the weld metal and the base metal Differently, the welding of aluminum-magnesium-gold produces brittle Mg2Si in the weld, which reduces the plasticity and corrosion resistance of the joint.

Uses: Commonly used as filler material for argon arc welding and oxygen-acetylene gas welding of aluminum alloy workpieces and castings other than aluminum-magnesium alloys, especially for heat-treated aluminum alloys that are prone to thermal cracks, and can obtain better results.

SAL5356 is usually used as ALMg5, which is an aluminum alloy filler metal containing 5% magnesium. It can be used for MIG or TIG welding. It has good seawater corrosion resistance and can generally be applied to base metals 5050, 5052, 5083 , 5356, 5454 and 5456 welding. It is white in color after anodizing and has a tensile strength of 290MP.

Performance characteristics: This product is an alloy welding wire containing 5% magnesium. It is a general-purpose welding material with a wide range of uses. It is suitable for welding or surface surfacing welding of cast and forged aluminum alloys with 5% magnesium. It has high strength and can Good forgeability and good corrosion resistance. This product also provides good color matching for anodized welds.

Uses: bicycles, aluminum scooters and other sports equipment, locomotive carriages, chemical pressure vessels, ordnance production, shipbuilding, aviation and other industries.

Attention should be paid to the selection of aluminum welding wire:

1) Crack sensitivity of welded joints

The direct factor affecting crack sensitivity is the matching of base metal and welding wire. The weld metal with a melting temperature lower than that of the base metal can be selected to reduce the crack sensitivity of the weld metal and the heat-affected zone. For example, when welding 6061 alloy with a silicon content of 0.6%, the same alloy is used as the weld, and the crack sensitivity is very high.

However, ER4043 welding wire with 5% silicon content has good crack resistance because its melting temperature is lower than that of 6061 alloy and it has higher plasticity during cooling. In addition, the weld metal avoids the combination of magnesium and copper because of the high crack susceptibility of Al-Mg-Cu.

2) Mechanical properties of welded joints

The strength of industrial pure aluminum is the lowest, the 4000 series aluminum alloy is in the middle, and the 5000 series aluminum alloy has the highest strength. Although aluminum-silicon welding wire has high crack resistance, the plasticity of silicon-containing welding wire is poor. Therefore, silicon-containing welding wire should be avoided for joints that require plastic deformation after welding.

3) Performance of welded joints

In addition to the composition of the base metal, the choice of filler metal is also related to the geometry of the joint, the corrosion resistance requirements during operation, and the appearance requirements of the weldment. For example, welded containers for storing hydrogen peroxide require high-purity aluminum alloys in order to provide good corrosion resistance to the container or to prevent contamination of it by the stored product. In this case, the filler metal must be at least as pure as the parent metal.

Generally speaking, ER4043 and er5356 mig wire are the most widely used aluminum alloy welding wires in aluminum alloy welding. We can choose more suitable welding wire according to the application requirements after welding.

A Better Choice: 5182 Aluminum Sheet for Fuel Tank

 The 5000 series aluminum alloy has as good corrosion resistance and weldability. The tank body made of aluminum alloy can transport various liquids or liquefied gas without any protective coating inside, and because there is no corrosion, the oil quality is guaranteed.

Aluminum alloy has good electrical conductivity and rarely accumulates static electricity on the tank body, so sparks will not be generated and cause explosions, and aluminum alloy can well absorb the instantaneous capacity generated by the tank body when it collides.

5083, 5754, 5454, 5059 and 5182 aluminium sheet are a common choice for making oil tankers and other chemical transport vehicles. They have the characteristics of large size, medium strength, high-quality surface, high formability, and has good corrosion resistance and welding performance, and recyclability. The toughness and strength of 5083-H321 aluminum alloy will increase at low temperature, which is very suitable for use in storage tanks of liquefied natural gas (LNG) in transport ships.

5182 aluminum plate for oil tanker is the latest high-magnesium alloy tanker specially designed for European dangerous goods road transport agreement in recent years. Its tensile strength and elongation are relatively high. When 5182 aluminum alloy is used for welding, the mechanical properties in welding can reach the minimum values specified for the base metal. The excellent quality of the 5182 alloy plate improves the safety of the aluminum alloy tanker.

What is the temperature 5182 aluminum alloy tank truck can undertake? It can withstand temperature up to 560 degrees Celsius. However, when the temperature exceeds 550 degrees Celsius, the tanker will basically become very brittle, soft, deformed, and have no bearing pressure.

Special requirements for aluminum alloy tank trucks

1. Process requirements

In addition to solving the requirements of special workshops, equipment, skilled personnel, supply of aluminum alloy materials and production technology, the production of aluminum alloy tank cars also requires a large amount of capital investment, especially the introduction of new production and processing technology for aluminum alloy tank cars.

2. Material requirements

At present, most manufacturers mainly use 5083 aluminum alloy plate as the material of the tank body, but the use of 5182 alloy can better reflect its corrosion resistance and welding performance, and under the same loading quality, the wall thickness of the tank body can be thinner and the weight is lighter.

Where to Buy Cigarette Packing Aluminum Foil

 The use of aluminum in the tobacco packaging industry is mainly the aluminum foil for the cigarette inner packaging. The cigarette packing aluminum foil can better prevent moisture and mildew, and keep dryness and taste. The thickness of the aluminum foil is 0.006mm to 0.007mm. Generally, aluminum foil with a thickness of 0.006mm is used. The temper is soft and has good extensibility.

Aluminum foil has very good protective properties. Aluminum foil paper cigarette boxes hardly absorb any aroma substances. Other materials such as metallized (coated) paper or printed paper cannot achieve similar quality and ability to protect aroma. In addition, aluminum foil paper used as the inner lining paper of cigarette packaging has good fluidity on the packaging machine, and can maintain high production efficiency.

1235 aluminum foil is a main kind of cigarette aluminum foil papers. Its aluminum content is not less than 99.35%. It has good anti-rust properties, formability, and weldability. It is also of few pinholes, low cost, good shape and stable chemical properties.

The alloy composition of 1235 aluminum foil and 8011 aluminum foil is different. The difference in process lies in the annealing temperature. The annealing temperature of 1235 aluminum foil is lower than that of 8011 aluminum foil, but the annealing time is basically the same. The tensile strength of 8011 aluminum foil is higher than that of 1235 aluminum foil. At the same time, the elongation of 8011 aluminum foil is not much different from that of 1235 aluminum foil, but slightly higher.

At present, the domestic production of 6~7μm light gauge aluminum foil generally uses 1235 aluminum, while European and American manufacturers generally use AA8079 alloy. Compared with AA1235 alloy, AA8079 alloy has higher content of Fe and Si, which has higher mechanical properties and higher production efficiency.

Difficult control of thickness error is a feature of aluminum foil rolling. The thickness difference of 3% is not difficult to control in the production of plates and strips, but it is more difficult to control in the production of aluminum foil.

As the thickness of the aluminum foil is thinned, many micro-conditions can be affected, such as temperature, oil film, oil and gas concentration, etc. The only way to adjust the thickness of aluminum foil is tension and speed. These factors have all caused the difficulty in thickness control of aluminum foil rolling.
