The 3xxx series aluminum coil is also known as aluminum manganese alloy. The content of manganese is 1-1.5%. It is a widely used rust-proof aluminum alloy series. The 3 series aluminum alloy coil has higher strength than pure aluminum alloy, although it cannot be heat treated to enhance performance , But it has good plasticity after cold working (under cold rolling mill ) and annealing process, because it has good corrosion resistance and welding performance, it can be used in many industries, such as building decoration industry, electronic manufacturing , Automobile manufacturing, etc.

The main brands commonly used in 3 series aluminum coil are 3003 aluminum coil, 3004 aluminum strip, 3104 aluminum sheet, 3005 aluminum plates, 3105 aluminum plates, etc. Among them, the largest amount is 3003 aluminum alloy. The 3003 aluminum plate is easy to process and has good rust prevention. It can be coated with color paint on the surface of the original aluminum to make various decorative curtain wall panels and indoor ceiling ceiling buckle plates. Roof tile color aluminum tile is made by bending the tile press, which is light and durable and has a longer life than 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 aluminum plates of 3003 H24 to replace 5052 to make separators in the fuel tank that do not require pressure, reducing costs without affecting the use. The strength of 3004 alloy is higher than 3003, and the forming performance is better. It can be used as the tank body of all-aluminum cans, and the device for the production and storage of liquids in chemical industry. 3104 alloy and 3004 alloy are very similar in composition, high strength and easy to process. In the TV manufacturing industry, 3104-O sheet is often used to make TV liquid crystal backplanes, punching convex hulls, adding electronic components, and forming dense oxidation after forming 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 the more high-end color coated aluminum coil. It is produced in the building materials industry, roof partitions, movable board houses, etc., and can also be used to produce heat sinks and internal parts for air conditioners, refrigerators, etc. 3105 alloy can be mainly used for making stamped parts such as bottle caps and caps.
