The strength of 6063A aluminum plate is lower than that of 6061, and its extrudability is good. It can be used as a shape with complex cross-sectional shapes. It has good corrosion resistance and surface treatment.

1. Strengthened by heat treatment, high impact toughness, insensitive to lack.

2. It has good thermoplasticity and can be extruded at high speed into complex, thin-walled and hollow profiles 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. That is, it can be quenched by spraying water or piercing water. Thin-walled parts (6 less than 3mm) can also be air quenched.

3. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Among the heat-treatable aluminum alloys, the Al-Mg-Si alloy is the alloy that has no stress corrosion cracking phenomenon in the 6063A aluminum plate.

4. After processing, the surface is very smooth and easy to anodize and color. The disadvantage is that if it is parked at room temperature for a period of time after quenching, it will have an adverse effect on the strength (parking effect).
