6063 aluminum alloy (channel aluminum material) is an Al-Mg-Si series high plasticity alloy with magnesium and silicon as the main alloying elements, with the following characteristics:
Chemical composition
Magnesium content: 0.45%-0.9%
Silicon content: 0.2%-0.6%
Other elements: copper ≤0.1%, zinc ≤0.15%, manganese ≤0.15%, etc. ‌
Mechanical properties
‌Tensile strength‌: ≥205MPa
‌Yield strength‌: ≥170MPa
‌Elongation‌: ≥9% ‌
Process characteristics
‌Heat treatment strengthening‌: wide quenching temperature range, low sensitivity, can be used for water spray, wind quenching and other cooling methods
‌Extrusion performance‌: suitable for thin-walled, hollow profiles with complex cross-section shapes
‌Welding and corrosion resistance‌: no tendency to stress corrosion cracking, easy to anodize and color the surface ‌
Application scenarios
Mainly used in building doors and windows, curtain wall frames and other fields with high requirements for mechanical properties, weather resistance and decorative properties.
