Update time:2022-06-29 10:59:04Number of clicks:0次
1 Series: features: more than 99.00% aluminum, good conductivity, good corrosion resistance, good welding performance, low strength, can not be strengthened by heat treatment Scope of application: high purity aluminum (containing more than 99.9% aluminum) is mainly used for scientific experiments, chemical industry and special purposes.

West Aluminum - West Aluminum Industry Telecom: 1 Series: features: more than 99.00% aluminum, good conductivity, good corrosion resistance, good welding performance, low strength, can not be strengthened by heat treatment Scope of application: high purity aluminum (containing more than 99.9% aluminum) is mainly used for scientific experiments, chemical industry and special purposes.

2 Series: features: aluminum alloy with copper as the main alloying element Manganese, magnesium, lead and bismuth are also added for machinability. For example: 2011 alloy, pay attention to safety protection (harmful gas will be generated) during melting and refining. 2014 alloy aerospace industry, high strength. The strength of 2017 alloy is a little lower than that of 2014 alloy, but it is easier to process. 2014 can be strengthened by heat treatment. Disadvantages: serious intergranular corrosion tendency. Scope of application: aviation industry (2014 alloy), screw (2011 alloy) and industries with high service temperature (2017 alloy).

3 Series: features: aluminum alloy with manganese as the main alloy element can not be strengthened by heat treatment, with good corrosion resistance and welding performance. Good plasticity. (close to super aluminum alloy). Disadvantages: low strength, but can be strengthened by cold work hardening. It is easy to produce coarse grains during annealing. Scope of application: oil guide seamless pipe (3003 alloy) and can (3004 alloy) used in aircraft.

4 series: mainly silicon, not commonly used. Some 4 series alloys can be strengthened by heat treatment, but some 4 series alloys cannot be heat treated.

5 Series: features: mainly magnesium. It has good resistance, welding performance and fatigue strength. It cannot be strengthened by heat treatment, but can only be improved by cold working. Scope of application: handle of lawn mower, fuel tank duct of aircraft, bulletproof vest.

Generally, the shoe rack at the middle end and above is basically 6-series or 7-series

6 Series: features: mainly magnesium and silicon. Mg2Si is the main strengthening phase and the most widely used alloy at present. 6063 and 6061 are used most, others are 6082, 6160, 6125, 6262, 6060, 6005 and 6463. 6063, 6060 and 6463 have low strength in the 6 series. 6262, 6005, 6082 and 6061 have higher strength in the 6 series. The frame at the middle end of cyclone 2 is 6061. It has the following characteristics: medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrude and form) and good oxidation and coloring performance. Scope of application: energy tools (such as: car luggage rack, door, window, body, radiator, compartment shell)

7 Series: features: mainly zinc, but sometimes a small amount of magnesium and copper are added. The superhard aluminum alloy contains zinc, lead, magnesium and copper alloys, which are close to the hardness of steel. The extrusion speed is slower than that of 6 series alloy, and the welding performance is good. 7005 and 7075 are the highest grades in the 7 series and can be strengthened by heat treatment. Scope of application: Aviation (aircraft load-bearing components, landing gear), rockets, propellers, aerospace ships.
