3 시리즈 알루미늄 합금은 알루미늄-망간 합금이라고도 합니다.. 망간 함량은 1-1.5%. 널리 사용되는 녹슬지 않는 알루미늄 합금 시리즈입니다.. 3 시리즈 알루미늄 합금의 강도는 순수 알루미늄 합금의 강도보다 높습니다.. , 그러나 냉간 가공 후에는 가소성이 좋습니다. (냉간 압연) 그리고 어닐링 과정, because of its good corrosion resistance and welding performance, it can be used in many industries, such as architectural decoration industry, electronic manufacturing industry , automobile manufacturing, 등.
The main grades commonly used in 3 series aluminum alloys are 3003 알루미늄 판, 3004 알루미늄 판, 3104 알루미늄 판, 3005 알루미늄 판, 3105 알루미늄 판 등등. 그 중, 그만큼 3003 grade aluminum alloy is the most used. 그만큼 3003 aluminum plate is easy to process and has good rust resistance. It can be coated with colored paint on the surface of the original aluminum to make various decorative curtain wall panels, and aluminum ceiling gussets for indoor use. Roof color aluminum tiles are made by bending with a tile press, which is light and durable, and has a longer lifespan than steel.
가격 3003 is cheaper than that of 5052, and its welding performance is also very good. Some truck fuel tank material manufacturers also use 3003H24 aluminum plate to replace 5052 to make partitions in the fuel tank that do not need to bear pressure, which reduces the cost without affecting the use.
의 힘 3004 alloy is higher than that of 3003, and its formability is better. It can be used as the tank body of all-aluminum pop cans, and the device for producing and storing liquids in chemical industry. 3104 alloy and 3004 alloy are very similar in composition, high in strength and easy to process. In the TV manufacturing industry, 3104-O plates are often used to make TV LCD backplanes, stamping convex hulls, adding electronic components, and forming dense oxidation after forming 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, prefabricated houses, 등., and can also be used to produce heat sinks and internal parts such as air conditioners and refrigerators. 3105 alloy can be mainly used to make stamping parts such as bottle caps and caps.
