Brief introduction of application of 3 series aluminum alloy plate
- Dec 20, 2018 -

The 3 series aluminum alloy is also called aluminum manganese alloy, and the content of manganese element 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 can not be heat treated and strengthened. However, it has good plasticity after cold working (cold rolling mill rolling) and annealing process. Because it has good corrosion resistance and welding performance, it can be used in many industries, such as building decoration industry, electronics manufacturing. , automobile manufacturing, etc.

The main brands commonly used in 3 series aluminum alloys are 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, 3105 aluminum plate, and the like. The largest amount is aluminum alloy of 3003 grade. The 3003 aluminum plate is easy to process and has good rust prevention. It can be coated with colored paint on the original aluminum surface to make various decorative curtain wall panels, as well as indoor aluminum ceiling panels. The tile machine is bent to make the roof color aluminum tile, which is light and durable, and has a longer life than steel.

The price of 3003 is cheaper than that of the 5052, and the welding performance is also very good. Some truck tank manufacturers also use the 3003H24 aluminum plate to replace the non-pressure-bearing separator in the 5052 fuel tank, which reduces the cost without affecting the use. The 3004 alloy has a strength higher than 3003 and has better forming properties. It can be used as a tank for all-aluminum cans, and a device for producing and storing liquids for chemical industry. The composition of 3104 alloy and 3004 alloy is very similar, the strength is high and it is easy to process. In the TV manufacturing industry, the 3104-O plate is often used to make TV LCD backsheet, stamping convex hull, adding electronic components, and forming dense oxidation after molding oxidation. The film not only resists corrosion and oxidation, but also has good insulation properties, that is, reduces the total weight of the finished product and ensures good heat dissipation performance. 3005 alloy is used as a relatively high-end color coated aluminum coil. It is made in the building materials industry, roof partition, movable board room, etc. It can also produce air conditioners, refrigerators and other heat sinks, internal parts and so on. 3105 alloy can be mainly used for making stamped parts such as caps and caps.
