1235 Aluminum Foil for Lithium Battery

 Aluminum foil battery acts as a positive current collector in lithium batteries due to its good properties. Battery aluminum foil has the characteristics of good conductivity, soft texture, cost advantage, stable performance at high potential.

The above characteristics are well adapted to the requirements of power batteries for current collectors. The power batteries currently used in new energy vehicles include ternary lithium batteries and lithium iron phosphate batteries, both of which are lithium-ion batteries.

Battery aluminum foil has a low weight and cost, and is relatively secretive among the components of lithium batteries. Battery aluminum foil accounts for 5% by weight, followed by positive electrode materials, negative electrode materials, electrolytes, and copper foil.

The cost accounts for about 3% of the total cost of lithium batteries, followed by lithium battery cathode materials, separators, negative electrode materials, copper foil, and electrolytes. The low weight and cost ratio often make people ignore its importance.

To further illustrate the importance of battery aluminum foil, we can compare it with other materials. In terms of chemical properties, the aluminum surface has a dense oxide layer and a high chemical potential, which can prevent the oxidation of the current collector and corrosion by the electrolyte, and at the same time, the lithium insertion reaction (LiAL alloying reaction) will not occur.

In terms of mechanical properties, it is easy to process, has good mechanical strength, can be welded and riveted, and has a soft texture, which can ensure that the pole piece does not break during winding, and has good thermal and electrical conductivity. In terms of cost, it has large reserves. The cost accounts for only 3% of the total cost of lithium batteries and is not a heavy metal or strategic metal resource.

Battery aluminum foil has higher purity. Currently, the battery aluminum foil produced in the market is mainly made of 1060, 1070, 1100 and 1235 aluminum foil. The above alloys all belong to the 1000 series. This series of alloys contains a large amount of aluminum, and the purity can reach more than 99.00%. Since it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries.

Is The Aluminium Strip Easy to Scratch

 Aluminium strip is a thin but strong metal strip made of aluminum alloy and is widely used in construction, electronics and packaging. However, the surface of aluminum strips is prone to scratching problems. So, why does aluminum strip scratch easily? How can we prevent this problem?

One of the reasons why the surface of aluminum strips is easily scratched is due to the relative softness of the aluminum alloy. Aluminum metal is less hard than other metals, such as steel. This makes the aluminum strip more susceptible to scratches by sharp objects on the surface. Accidental use of sharp objects, such as keys or pins, to rub against the surface of the aluminum strip can cause visible scratches.

On the other hand, the surface of the aluminum strips for sale is also susceptible to corrosion by chemicals. Some chemicals, such as acids, salts, alkali, etc., can cause oxidation reactions in aluminum strips. This reaction can lead to a harsh oxide layer on the surface, which affects the overall aesthetics of the aluminum strip. In addition, some strong acidic or alkaline solutions are more likely to cause deep corrosion, causing the aluminum strip to lose its original strength and durability.

How to effectively avoid scratches on the surface of aluminum strips? Firstly, we can apply a protective coating to the surface of the aluminum strip. This coating can increase the hardness of the aluminum strip to a certain extent, making it more resistant to scratches. In addition, this coating prevents chemical corrosion of the aluminum strip. In terms of coating selection, environmentally friendly coatings are recommended.

When we use aluminum strips daily, we should pay attention to avoid direct contact with sharp objects. For example, we can place the aluminum strip in a place free of sharp objects, or wrap it in a special protective cover to reduce the risk of scratches. In addition, care should be taken during handling and storage to avoid collision with hard surfaces or other sharp objects.

For scratched aluminum strips, we can try some repair methods. For example, minor scratches can be polished using a metal polish to eliminate or reduce the appearance of the scratch. For deeper scratches, consider using aluminum tape repair compound or decals to repair localized scratches. However, these methods are only suitable for small scratch repairs. Larger scratches may require a more complete repair or replacement. Welcome to leave message below to inquire aluminum ceiling strips price.

 Aluminum alloys are one of the most widely used materials in aviation field. hey have good mechanical properties and process characteristics, and are characterized by high strength, light weight, and good toughness. They are one of the most important members of the civil aircraft structural material family.

The main features of Al alloy 2024 are large-scale and integrated, thin-walled and lightweight, precise cross-sectional dimensions and geometric tolerances, and uniform and high-quality structural properties. Aluminum alloys used in aerospace are mainly high-strength aluminum alloys, heat-resistant aluminum alloys, and corrosion-resistant aluminum alloys. High-strength aluminum alloys are mainly used in aircraft fuselage components, engine nacelles, seats, control systems, etc.

Al alloy 2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium system. It contains 4.5% copper, 0.6% manganese and 1.5% magnesium. Its composition is reasonable and its overall performance is good. It is the most heavily used among the duraluminum alloys. 2024 aluminum alloy is commonly used in T3 and T4 tempers, which have high plasticity, fatigue life, fracture toughness and resistance to fatigue crack growth, but poor corrosion resistance.

2024 T3 aluminum not only has high strength, but also has excellent fatigue resistance. Welding is generally not recommended. Typical uses for 2024-T3 Alclad aluminum sheet are fuselage and wing skins, roofs, aircraft structures, and repair and restoration. Its ultimate strength is 62,000 PSI and shear strength is 40,000 PSI.

Aircraft manufacturers use high-strength alloys (mainly Alloy 7075) to strengthen aluminum aircraft structures. Aluminum alloy 7075 has copper (1.6%), magnesium (2.5%) and zinc (5.6%) for ultimate strength, but the copper content makes it very difficult to weld. 7075 aluminum has the best machining performance and can achieve very good results. The ultimate strength is 33000 PSI(-0) and 82000 PSI(-T6), and the shear strength is 22000 PSI(-0) and 49000 PSI(-T6).

7075 aluminum sheet’s common tempers are T6, T73, T76 and T74. 7075 t6 alloy has the highest strength, low fracture toughness, and is sensitive to stress corrosion cracking. It is generally not recommended for use in low temperature applications. The thermal conductivity of the material is related to its state. At 25℃, the thermal conductivity of the 7075-t6 is 124W/(m·℃), while that of the T73 material is higher, 156W/(m·℃). The specific heat capacity of 7075-T6 alloy (at 25℃) is 796J/(kg·℃).

Aluminum Alloy 6101 5754 for High-speed Railway

 High-speed rail carriages are welded with aluminum, and some high-speed rail lines pass through high-cold zones of minus 30 to 40 degrees Celsius; some instruments, equipment and daily necessities on Antarctic research ships are made of aluminum and need to withstand temperatures of minus 60 to 70 degrees Celsius. Can they function properly in such a cold environment? No problem, aluminum alloys are the latest afraid of cold and heat.

Aluminum alloys are the best low-temperature materials. They have no low-temperature brittleness. They are not as obvious as ordinary steel and nickel alloys. Although the steel’s strength properties increase as the temperature decreases, its plasticity and toughness decreases with the decrease of temperature, that is, it has obvious low-temperature brittleness. However, the aluminum alloys’ mechanical properties increase significantly with the decrease of temperature, regardless of the composition of the material, whether it is cast aluminum alloy, deformed aluminum alloy, powder metallurgy alloy, or composite material.

Aluminum alloys for high-speed rail carriages include Al-Mg series 5005 alloy sheets, 5052 alloy sheets, 5083 alloy sheets and profiles, Al-Mg-Si series 6061 alloy sheets and profiles, aluminum alloy 6101,6063 alloy profiles, Al-Zn-Mg series 7N01 alloy plates and profiles, and 7003 alloy profiles. The standard states are O, H14, H18, H112, T4, T5, and T6.

No matter what kind of aluminum alloy, its mechanical properties increase as the temperature decreases, so aluminum is an excellent low-temperature structural material, used for rocket cryogenic fuel (liquid hydrogen, liquid oxygen) storage tanks, liquefied natural gas (LNG) transportation ships and shore-based storage tanks, low-temperature chemical product containers, cold storage, refrigerated trucks, etc.

The aluminum plates used in the current manufacturing and maintenance of rail vehicle bodies include 5052, 5083, 6061, 5454 aluminum and the extruded profiles used include 5083, 6061, 7N01, etc. In addition, some new alloys such as 5059, 5383, 6082, etc., also has applications. It is best to use friction stir welding (FSW), which not only has high welding quality, but also does not require welding wire.

We can divide the aluminum alloys of the car bodies into according to the train operating speed: those used for vehicles with speeds <200km/h can be called first-generation alloys. They are conventional alloys and are mostly used to manufacture urban rail vehicle bodies, such as 6063, 6061 and 5083; second-generation aluminum alloys such as 6N01, 5005, 6005A, 7003, 7005 alloy, etc. are used to manufacture high-speed rail vehicle bodies with speeds of 200km/h~350km/h; third-generation alloys are 6082. Haomei Aluminum has all these aluminum alloys. Welcome to leave message to inquire what you need.

Marine Grade Aluminum Diamond Plate and Marine Pipes

 The aluminum tread plates are mostly made of 1060, 3003, 5052 and 6061. In comparison, the 1 and 3 series aluminum checker plates have lower hardness and slightly poorer wear resistance, and are mostly used in ordinary environments and applications where the anti-rust requirements are not strict.

The cabins of the shipbuilding industry all choose marine grade aluminum diamond plates, which have good anti-skid effect, strong anti-rust ability and light weight. 6061 patterned plate is a patterned aluminum plate with high hardness. The hardness is around 95HB in the T6 state. The bending performance is not good, but the hardness and strength are good.

5083 marine grade aluminum diamond plate has good corrosion resistance and anti-rust performance, and can adapt well to high-strength and high-corrosion resistance occasions. It has good application effects in ships, vehicles, and work platforms.

The 5086 marine aluminum tread plate after surface embossing is also the best material for spiral stairs, pedals, refrigerated truck sidings and floors on large ships. 5086 aluminum sheet has excellent corrosion resistance. At the same time, because of the various patterns embossed on the surface, such as 2 bars, 3 bars, 5 bars,etc., it plays a more critical anti-slip property.

6061 and 6082 are two alloys to make marine aluminum extrusions. They good formability, weldability, machinability, and medium strength,which can still maintain good operability after annealing. They are mainly used in mechanical structures, including bars, plates, pipes and profiles.

Aluminum Plate and Aluminum Coil for Tankers

 Compared with ordinary carbon steel and stainless steel tank trucks, aluminum alloy tank trucks can not only significantly reduce the weight of the vehicle, improve transportation efficiency, but also extend the service life of the tank. The aluminium coil for tankers are usually 5083, 5182, 5754, 5454,etc.

5083 aluminum alloy is with high strength, high toughness, corrosion resistance, easy processing, good thermal conductivity and fatigue resistance. It is a good choice for aluminum for tank car bodies. 5083 ultra-wide aluminum plate is widely used in the tanker body, because tank trucks are generally longer, with a length of 4-12.5 meters.

5454 aluminum alloy plate is an aluminum-magnesium alloy that is suitable for use under high temperature conditions and has good strength and corrosion resistance at high temperatures. When the temperature is higher than 135°C for long-term use, 5454 (0/H111) has better strength than 5083 aluminum-magnesium alloy.

At present, most tanker truck manufacturers mainly use 5083 aluminum plate for tanker head, tanker body and the use of 5182 plates can better reflect its corrosion resistance and welding performance, and under the same loading quality, the tank wall thickness can be thinner and the weight can be higher light.

The 50583 and 5182 aluminum coil required for tank bodies of oil tankers and other chemical transport vehicles has the characteristics of large size, medium strength, high quality surface and high formability. In particular, the toughness and strength of 5083-H321 aluminum alloy will increase at low temperatures, making it very suitable for use in liquefied natural gas (LNG) storage tanks on transport ships.

5754 aluminum sheet can be used to make tank truck bodies and bulkheads. The magnesium content of 5754 aluminum plate is higher than that of 5052, so the machinability is better. The silicon content of 5754 aluminum plate is also higher than that of 5052. The silicon content affects the forging function and corrosion resistance of aluminum alloy, so the 5754 aluminum plate has better forging properties and corrosion resistance.
