6063 aluminum alloy belongs to Al-Mg-Si alloy and has a wide range of applications. Especially in the construction industry, it is inseparable from this alloy and is a promising alloy. Good corrosion resistance, excellent weldability, good cold workability and medium strength.

The main alloying elements are magnesium and silicon, which have excellent processing properties, excellent weldability, extrusion and electroplating properties, good corrosion resistance, toughness, easy polishing, color film, excellent anodizing effect, and are typical. Extruded alloy. 6063 aluminum alloy profiles are widely used in architectural profiles, irrigation pipes, vehicles, gantry, furniture, etc. due to their good plasticity, moderate heat treatment strength, good welding performance and gorgeous color on the surface after anodizing. Pipes, rods and profiles for elevators, fences, etc.

It is a low alloyed Al-Mg-Si high plasticity alloy. Has many valuable features: 1. Heat treatment strengthening, high impact toughness, can not be sensitive to lack of. 2. It has excellent thermoplasticity and can be extruded at high speed into a complex structure. Thin wall. Hollow various profiles or forged forgings with complex structure, wide quenching temperature range, low quenching sensitivity, after extrusion and forging demoulding, As long as the temperature is higher than the quenching temperature. That is, it can be quenched by spraying water or water. Thin-walled parts (6<3mm) can also be subjected to wind quenching. 3. Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency. In the heat-treated reinforced aluminum alloy, the Al-Mg-Si alloy is an alloy in which stress corrosion cracking is not observed. 4. The surface after processing is very smooth and easy to anodize and color. The disadvantage is that if it is aged at room temperature for a period of time after quenching, it will have an adverse effect on the strength (parking effect).
