6061 6063
Features: Mainly magnesium and silicon.
Mg2Si is the main strengthening phase and is currently the most widely used alloy.
6063 and 6061 are the most commonly used, followed by 6082, 6160, 6125, 6262, 6060, 6005, and 6463. 6063, 6060, and 6463 have relatively low strength in the 6 series. 6262, 6005, 6082, and 6061 are relatively strong in the 6 series. The middle shelf of Tornado 2 is 6061

Characteristics: medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrusion) and good oxidation and coloring performance.
Application scope: means of transportation (such as car luggage racks, doors, windows, bodywork, radiators, box casings, mobile phone cases, etc.)
