The 6-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 2-series aluminum alloy, and the process performance is better than that of the 2-series aluminum alloy, but the corrosion resistance is deteriorated, and the alloy has good forging properties. The most widely used 6-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.
At present, 6 series aluminum alloy grades are produced: 6005, 6060, 6061, 6063, 6082, 6201, 6262, 6463, 6A02. The following is a detailed introduction to their respective uses.
The main purpose of 6 series aluminum alloy
6005 extruded profiles and pipes are used for structural parts that require strength and height greater than 6063 alloys, such as ladders, TV antennas, etc.
