6063 aluminum alloy belongs to Al-Mg-Si alloy, which is widely used, especially in the construction industry, it is the most promising alloy. Good corrosion resistance, excellent weldability, good cold processing ability, and has moderate strength.
The main alloy elements are magnesium and silicon, with excellent machining properties, excellent weldability, extrusion and electroplating properties, good corrosion resistance, toughness, easy polishing, color film, anode oxidation effect is excellent, is a typical extrusion alloy. 6063 aluminum alloy profiles with its good plasticity, moderate heat treatment strength, good welding performance and anodized surface gorgeous color and color and many other advantages are widely used in building profiles, irrigation pipes, for vehicles, benches, furniture, lifts, fences and other pipes, rods, profiles.
It is a low alloying Al-Mg-Si high plastic alloy. It has many valuable characteristics: 1. Heat treatment enhancement, high impact toughness, sensitive to lack. 2. It has excellent thermoplasticity and can be extruded into complex structure at high speed. Thin wall. Hollow profiles or forging into complex structure forgings, quenching temperature range is wide, low quenching sensitivity, extrusion and forging after demoulding, as long as the temperature is higher than the quenching temperature. Quenching can be done by spraying or penetrating water. Thin wall parts (6<3mm) can also implement wind quenching. 3. Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency, in the heat treatment can strengthen aluminum alloy, Al-Mg-Si alloy is the only alloy without stress corrosion cracking phenomenon. 4. After processing, the surface is very smooth and easy to anodize and stain. Its disadvantage is that after quenching, if it is parked at room temperature for a period of time and then aging, it will bring adverse effects on the strength (parking effect).
