6063 aluminum plate is widely used in the frame of building aluminum doors and windows and curtain walls. In order to ensure that doors and windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance, the comprehensive performance requirements of aluminum alloy profiles are much higher than industrial profiles. standard.

① 6063 is a representative alloy for extrusion. Its strength is lower than that of 6061, and its extrudability is good. It can be used for shapes with complex cross-sectional shapes. It has good corrosion resistance and surface treatment.

② It is a low-alloyed Al-Mg-Si high-plastic alloy. Has many valuable features:

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

2. 6063 aluminum plate has good thermoplasticity and can be extruded at high speed into complex, thin-walled and hollow profiles or forged into forgings with complex structure. It has a wide quenching temperature range and low quenching sensitivity. After extrusion and forging demoulding, as long as The temperature is higher than the quenching temperature. It can be quenched by water spray or water penetration. Thin-walled parts (6 less than 3mm) can also be air quenched.

3. Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency. Among the heat-treatable-strengthened aluminum alloys, Al-Mg-Si alloys are 6063 alloys that have no stress corrosion cracking phenomenon.

4. The surface of 6063 aluminum plate is very smooth after processing, and it is easy to be anodized and colored. The disadvantage is that if it is aged at room temperature for a period of time after quenching, it will adversely affect the strength (parking effect).
