The 3 series aluminum plate is also called aluminum-manganese alloy. The manganese content is 1-1.5%. It is a widely used anti-rust aluminum alloy series. The strength of the 3 series aluminum alloy is higher than that of pure aluminum alloy, although it cannot be heat treated to strengthen the performance. , But it has good plasticity after cold working (under-cold mill rolling) and annealing process. Because of its good corrosion resistance and welding performance, it can be used in many industries, such as building decoration industry, electronic manufacturing industry , Automobile manufacturing, etc.
The main grades commonly used in 3 series aluminum alloys are 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, 3105 aluminum plate and so on. Among them, the 3003 aluminum alloy is the most used. The 3003 aluminum plate is easy to process and has good rust resistance. It can be used to roll paint on the surface of the original aluminum to make various decorative curtain wall panels and aluminum ceiling gussets for indoor use. The tile press is bent to make the roof color aluminum tile, which is light and durable, and has a service life better than that of steel.
The price of 3003 is cheaper than that of 5052, and the welding performance is also very good. Some truck fuel tank material manufacturers also use 3003H24 aluminum plates to replace the pressure-bearing partitions in the 5052 fuel tanks, reducing costs without affecting the use. The strength of 3004 alloy is higher than that of 3003, and its forming performance is better. It can be used as the body of all-aluminum cans, and a device for chemical production and storage of liquids. 3104 alloy and 3004 alloy are very similar in composition, high strength and easy to process. In the TV manufacturing industry, 3104-O state plates are often used to make TV LCD backplanes, punch convex hulls, add electronic components, and form dense oxidation after molding and oxidation. The film is not only resistant to corrosion and oxidation, but also has good insulation, which reduces the total weight of the finished product and ensures good heat dissipation performance.
3005 alloy is mostly used in relatively high-end color-coated aluminum coils. It is produced in the building materials industry, roof partitions, mobile board houses, etc., and can also be used to make air conditioners, refrigerators and other heat sinks, internal parts, etc. 3105 alloy can be mainly used to make punched parts such as bottle caps and caps.
