3000 series rust proof aluminum alloy plate is also called aluminum-manganese alloy aluminum plate, with a manganese content of 1-1.5%. It is a widely used rust-resistant aluminum alloy series. The strength of 3000 series rust proof aluminum alloy is higher than that of pure aluminum alloy. Although it cannot be strengthened by heat treatment, it has good plasticity after cold working (cold rolling) and annealing treatment. Due to its good corrosion resistance and welding performance, it can be used in many industries such as construction decoration, electronic manufacturing, and automobile manufacturing.
The commonly used main grades in the rust proof aluminum alloy plate are 3003 aluminum sheet, 3004 aluminum sheet, etc. The most widely used is the 3003 grade aluminum alloy. 3003 aluminum sheet is easy to process, has good rust resistance, can be roller-coated with colored paint on the original aluminum surface, and can be made into various decorative curtain wall panels and aluminum ceiling panels for indoor use. It can also be bent and made into roof colored aluminum tiles with a tile press machine. It is lightweight, durable, and has a longer lifespan than steel.
The price of 3003 rust proof aluminum alloy plate is relatively cheaper compared to 5052 aluminum plate, and it also has good welding performance. Some truck fuel tank manufacturers use 3003H24 aluminum sheets instead of 5052 aluminum sheet to make non-pressured baffles in the fuel tank, reducing costs without affecting the usage. 3004 aluminum alloy has higher strength than 3003 aluminum and better forming performance, and can be used as the body of all-aluminum cans and devices for producing and storing liquids used in the chemical industry. The composition of the 3104 aluminum alloy is very similar to that of the 3004 aluminium alloy, with higher strength and easy processing. In the television manufacturing industry, 3104 O state aluminum plates are commonly used to make LCD TV back panels, stamped convex bumps, add electronic components, and after forming oxidation, a dense oxide film can be formed, which is not only resistant to corrosion and oxidation, but also has good insulation, reducing the total weight of the finished product and ensuring good heat dissipation performance.
