Features of aluminum alloy

- Aug 16, 2017 -

1: Features: Aluminum 99.00% or more, good conductivity, good corrosion resistance, good welding performance, low strength, non-heat treatment to strengthen. Application: high purity aluminum (aluminum content of more than 99.9%) is mainly used for science Testing, chemical industry and special purpose.

2 Series: Features: Copper-based alloy containing aluminum. Manganese, magnesium, lead and bismuth are also added for machinability. Such as: 2011 alloy, in the smashing process should pay attention to safety protection (will produce harmful gases). 2014 alloy with days of aviation industry, high strength. 2017 alloy than the 2014 alloy strength is lower, but relatively easy to process. 2014 heat treatment enhanced. Disadvantages: serious intergranular corrosion tendency. Applications: Aviation industry (2014 alloy), screw (2011 alloy) and the use of high temperature industry (2017 alloy).

3 Series: Features: manganese as the main alloying elements of aluminum, non-heat treatment to strengthen, good corrosion resistance, good welding performance. Good plasticity. (Close to superalloy). Disadvantages: low strength, but can be hardened by cold work to strengthen the strength. It is easy to produce coarse grains during annealing. Applications: aircraft used in the oil-based seamless tube (3003 alloy), cans (3004 alloy).

4 series: the main silicon, not commonly used. Part 4 is heat-treated to strengthen, but there are some 4-series alloy heat-treatable. Hr

5 Series: Features: mainly magnesium. Good resistance to good performance, good welding performance, good fatigue strength, heat treatment can not be enhanced, only cold work to improve strength. Applications: Mower handle, aircraft fuel tank guide, body armor.

6 Series: Features: mainly magnesium and silicon. Mg2Si as the main strengthening phase, the most widely used alloy. 6063,6061 with the most, the other 6082,6160,6125,6262,6060,6005,6463. 6063,6060,6463 in the 6 series strength is relatively low. 6262,6005,6082,6061 in the 6 series of high strength. Features: medium strength, good corrosion resistance, good welding performance, good process performance (easy extrusion forming) oxidation coloring performance. Applications: cross energy tools (such as: car luggage racks, doors, windows, body, heat sink, between the box shell)

7 Department: Features: mainly zinc, but sometimes also add a small amount of magnesium, copper. Which is super-hard aluminum alloy is containing zinc, lead, magnesium and copper alloy close to the hardness of steel. Extrusion speed is slower than 6 series alloy, welding performance is good. 7005 and 7075 are the highest grades in the 7 Series, which can be heat treated. Applications: aviation (aircraft bearing components, landing gear), rockets, propellers, air spacecraft.
