6061 6063 Aluminium Sheet for Door Description
6061 aluminum plate: It has high content of magnesium (0.8%-1.2%) and silicon (0.4%-0.8%), contains a small amount of copper (0.15%-0.4%), and has a hard tensile strength of 316 MPa, which is suitable for high-load-bearing door frames and wind pressure-resistant structures. 6061 T6 aluminum plate increases the strength to more than 310 MPa, with good welding performance but strict process control is required.
6063 aluminum plate: The ratio of magnesium (0.45%-0.9%) and silicon (0.2%-0.6%) pays more attention to ductility, with a tensile strength of 295 MPa, but excellent extrusion molding ability, suitable for complex cross-section door frame design. 6063 aluminum alloy can simplify the process through conventional air cooling quenching, and the surface roughness is low after anodizing. 6063 polished aluminum plate can be used as a high-gloss decorative facade.
Prioritize load-bearing and safety: Choose 6061-T6 thick aluminum plate with a yield strength of 276 MPa, suitable for special doors such as fire doors and bulletproof doors;
Prioritize aesthetics and economy: Choose 6063-T5 aluminum plate, which reduces the overall cost by 15%-20%, and can be fully covered by RAL color system for oxidation coloring;
Adaptation to extreme environments: 6061 anodized aluminum plate (better corrosion resistance) is recommended in humid/high salt spray areas, and 6063 color-coated aluminum plate (stronger surface decoration) is preferred in dry areas.
