6063 is a low alloyed Al-Mg-Si high plastic alloy. It has many valuable characteristics:
1.Heat treatment strengthening, high impact toughness, insensitive to gaps.
2.It has good thermoplasticity, which can be extruded into various profiles with complex structure, thin wall and hollow at a high speed, or forged into forgings with complex structure. The quenching temperature range is wide and the quenching sensitivity is low. After extrusion and forging demoulding, as long as the temperature is higher than the quenching temperature, it can be quenched by spraying water or through water. Thin-walled parts (δ<3mm) can also be air-quenched.
3.Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency, in the heat treatment can strengthen the aluminum alloy, Al-Mg-Si alloy is the only alloy that has not found stress corrosion cracking phenomenon.
4. The surface after processing is very smooth and easy to anodize and color. The disadvantage is that after quenching, if it is parked at room temperature for a period of time, it will have an adverse effect on the strength in aging (parking effect).
