Yinsheung Deep Processing 2023-10-04 10:18 Published in Foshan
The chemical composition and processing properties of 6060 and 6063 aluminum alloys are similar, but not completely the same. The difference between the two lies in their strength. 6060 is a national standard aluminum alloy for doors and windows, while 6063 is a nationally licensed aviation aluminum alloy.

6063 aluminum alloy belongs to the Al Mg Si series alloy and has a wide range of applications, especially in the construction industry. It is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and moderate strength.
The main alloy elements are magnesium and silicon, which have excellent processing performance, excellent weldability, extrusion and electroplating properties, good corrosion resistance, toughness, easy polishing, coloring film, and excellent anodizing effect. They are typical extruded alloys. 6063 aluminum alloy profiles are widely used in building profiles, irrigation pipes, pipes, rods, and profiles for vehicles, platforms, furniture, elevators, fences, etc., due to their good plasticity, moderate heat treatment strength, good welding performance, and gorgeous surface color after anodizing treatment.
A low alloying Al Mg Si series high plasticity alloy. It has many valuable features: 1. Heat treatment strengthening, high impact toughness, and insensitivity to defects. 2. It has excellent thermoplastic properties and can be rapidly extruded into various profiles with complex structures, thin-walled and hollow sections, or forged into forgings with complex structures. It has a wide quenching temperature range and low quenching sensitivity. After extrusion and forging demolding, as long as the temperature is higher than the quenching temperature. It can be quenched by spraying water or penetrating water. Thin walled parts (6<3mm) can also be air quenched. 3. Excellent welding performance and corrosion resistance, with no tendency for stress corrosion cracking. Among heat treatable and reinforced aluminum alloys, Al Mg Si alloy is the only alloy that has not been found to exhibit stress corrosion cracking. 4. The surface after processing is very smooth and easy to anodize and stain. Its disadvantage is that if it is left at room temperature for a period of time after quenching and aged, it will have a negative impact on strength (parking effect)
