The 6000 series aluminum alloy is an aluminum alloy with magnesium and silicon as the main alloying elements and Mg2Si phase as the strengthening phase. The alloy has the advantages of medium strength, high corrosion resistance, no stress corrosion cracking tendency, good welding performance, unchanged corrosion performance in the welding zone, good formability and process performance. When the alloy contains copper, the strength of the alloy can be close to that of the 2000 series aluminum alloy, and the process performance is better than that of the 2000 series aluminum alloy, but the corrosion resistance is deteriorated, and the alloy has good forging properties.

The most widely used 6000 series alloys are 6061 and 6063 alloys, which have the best comprehensive properties. The main products are extruded profiles, which are the best extruded alloys. The alloys are widely used as building profiles. In addition to being widely used as structural and decorative materials for building doors, windows and curtain walls, it is also widely used as indoor furniture, toilets, radiators, elevator handrail profiles and general industrial pipes and bars.
