Dec 13, 2022
A brief introduction of 1-7 series aluminum alloy takes you into the large family of aluminum alloys
1 series: Features: containing more than 99.00% aluminum, good conductivity, good corrosion resistance, good welding performance, low strength, can not be strengthened by heat treatment, application: high purity aluminum (containing more than 99.9% aluminum) mainly used for scientific tests, chemical industry and special purposes.
2 series: Features: Aluminum alloy with copper as the main composite element. Manganese, magnesium, lead and mysto are also added for cutting properties. For example :2011 alloy, in the process of melting should pay attention to safety protection (will produce harmful gas). Alloy aerospace industry, high strength. The 2017 alloy is a little less strong than the 2014 alloy, but easier to work with. It can be strengthened by heat treatment. Disadvantages: Severe intergranular corrosion tendency. Application: Aviation industry (2014 alloy), screw (2011 alloy) and high temperature industry (2017 alloy)
Series 3: Features: Aluminum alloy with manganese as the main alloying element, can not be strengthened by heat treatment, good corrosion resistance, good welding performance. Good plasticity.
4 series: Mainly silicon, not commonly used. Some series 4 alloys can be strengthened by heat treatment, but some series 4 alloys cannot be heat treated.
5 series: Features: Mainly magnesium. Good resistance, good welding performance, good fatigue strength, not heat treatment to strengthen, can only cold processing to improve the strength. Applications: Handle of lawn mower, aircraft fuel tank conduit, body armor.
6 series: Features: Mainly magnesium and silicon. Mg2si is the most widely used alloy as the main strengthening phase. 1 use most, other 6082616612 5626 2606 6063606 0600 5646 3606 3, 6060, 6463 in 6 of strength is lower. The strength of 6262,6005,6082,6061 is relatively high in the 6 series. Cyclone No. 2 middle shelf is 6061 characteristics: medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrude forming) oxidation and coloring performance. Application: Energy tools (such as: car rack, door, window, body, radiator, compartment shell)
7 series: Features: mainly zinc, but sometimes also a small amount of added magnesium, copper. The superhard aluminum alloy is containing zinc, lead, magnesium and copper alloys close to the hardness of steel.The extrusion speed is slower than that of series 6 alloy, and the welding performance is better. 7005 and 7075 are the highest grades of the 7 series and can be strengthened by heat treatment. Application: aviation (aircraft load-bearing components, landing gear), rockets, propellers, spacecraft.
