Characteristics and applications of 3-series aluminium-manganese alloys

2022-12-21

3 series aluminium alloy sheet, also known as rust-proof aluminium sheet, the main alloying element is manganese. The representative grades are 3003 and 3004 aluminium sheets, which have higher strength than industrial pure aluminium sheets and good formability, fusibility and corrosion resistance. As it cannot be strengthened by heat treatment, cold working is mostly used to improve its mechanical properties. The strength of 3004 is superior to that of 3003. The main states are O, H12, H14, H16, H18, H19, H32, H34, H36, H38, etc.

3 series aluminium-manganese alloy characteristics.

3003 aluminum alloy is the most used, 3003 aluminum plate is easy to process, good rust prevention, can be rolled on the surface of the original aluminum colour paint, life better than steel. 3003 price is cheaper than 5052, welding performance is also very good, some truck fuel tank material manufacturers also use 3003H24 aluminum plate to replace 5052 production tank does not need to bear the pressure of the bulkhead, reduce costs and do not affect the use of. The strength of 3004 alloy is higher than 3003, better forming performance, higher strength and easy processing, forming oxidation can form a dense oxide film is not only resistant to corrosion and oxidation, there is good insulation, that is, to reduce the total weight of the finished product, but also to ensure a good heat dissipation performance.

3 series aluminium-manganese alloy uses.

Applicable to the application of industrial pure aluminium sheet as well as other areas requiring higher hardness, commonly used in kitchenware, food and chemical storage and transportation, heat sinks, home appliances (such as air conditioners, refrigerators, washing machines, etc.) and various other fields, is a more common series of aluminium alloy sheet. Among them, 3004 and 3104 aluminium strip is currently the mainstream material for the production of can bodies.
