6063 aluminum alloy material. The main alloying elements are magnesium and silicon. It has excellent processing performance, excellent weldability, extrusion and electroplating properties, good corrosion resistance, toughness, easy polishing and coloring, and excellent anodizing effect. It is a typical extrusion material. Pressed alloy. 6063 aluminum alloy profiles are widely used in building profiles, irrigation pipes, vehicles, benches, and furniture due to their good plasticity, moderate heat treatment strength, good welding performance, and gorgeous surface color after anodization. , tubes, rods and profiles for lifts, fences, etc. It has many valuable features: 1. Strengthened by heat treatment, high impact toughness, and insensitive to notches. 2. It has excellent thermoplasticity and can be extruded at high speed into various profiles with complex structures, thin walls, and hollows, or forged into forgings with complex structures. The quenching temperature range is wide and the quenching sensitivity is low. After extrusion and forging, as long as the temperature is higher than the quenching temperature, it can be quenched by water spraying or water penetration. Thin-walled parts (8<3mm) can also be air-quenched. 3. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Among heat treatment-strengthenable aluminum alloys, A1-Mg-Si alloy is the only alloy in which no stress corrosion cracking phenomenon has been found. 4. The surface after processing is very smooth and easy to anodize and color.
