    The 3 series aluminum alloy is also called aluminum-manganese alloy as 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, it has good plasticity after cold working (under-cold rolling mill) and annealing process. Because of its good corrosion resistance and welding performance, it can be used in many industries, such as building decoration,electronic manufacturing and automobile manufacturing etc.

    3003, 3004, 3005, 3104 and 3105 are well known by people and among which 3003 is the most common used 3xxx alloy. 3003 aluminum plate is easy to process and has good rust resistance. It can be used to roll paint on the surface to make various constructive materials like curtain wall panels, aluminum ceiling, venetian blind as well as ACP etc. 

    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 3003 H24 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 the forming performance is better. It can be used as the body of all-aluminum cans and as 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 plates are often used to make TV LCD backplanes, punch convex hulls, electronic components and form dense oxidation film 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, in the building materials industry, roof partitions, mobile board houses, etc. It 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.
