6063 Aluminum Sheet

6063 aluminum alloy is widely used in the construction of aluminum doors, windows and curtain walls. In order to ensure the high wind pressure resistance, assembly performance, corrosion resistance and decoration performance of doors, windows and curtain walls, the comprehensive performance requirements of aluminum alloy profiles are much higher than those of industry Profile standards.

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

2.It has excellent thermoplasticity, which can be extruded at high speed into complex structures, thin-walled, hollow profiles or forgings with complex structures. The quenching temperature range is wide and the quenching sensitivity is low.

3.Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency.

4.After processing, the surface is very smooth and easy to anodize and color.
