Aviation aluminum 6063 belong to Al-Mg-Si alloy, which can be heat-treated and strengthened. It has medium strength, strong corrosion resistance and no tendency of stress corrosion cracking. The tensile strength and yield strength of 6063 aluminum alloy at different temperatures are good, and the elongation is large.
6063 aluminum alloy has excellent weldability, which is applicable for gas welding, arc welding, contact spot welding and wire welding. In addition, it is easy to polish and has good anodizing effect.
6063 aluminum alloy is used as building profiles, irrigation pipes, extruded profiles for vehicles, benches, furniture, elevators, fences, etc., as well as decorative components for ships, airplane and automobile.
The common tempers of 6063 aluminum sheet are O, T4, T6 and T651. The alloy in T651 is stretched on the basis of T6 temper to eliminate internal stress and is more suitable for processing and forming.
O, T4, T6, T651
1. Found in the finer details of an aircraft, 6063 is mainly used for aesthetic and architectural finishes. It is used primarily for intricate extrusions.
2. 6063 aluminum sheet is a heat-treatable and strengthened aluminum alloy with medium strength, strong corrosion resistance, and no tendency to stress corrosion cracking. It can be used as a material for electric fuel pumps.
Among all electric fuel pump materials, the weight of the fuel pump made of aluminum alloy is the lightest, which is in line with the current trend of lightweight cars.
3. 6063 aluminum alloy is mainly used to manufacture the overall outline of the car body and the body of the tank truck. he aluminum car body has the advantages of light weight, heat resistance, good printing effect, and recyclability.
During the production process of 6063 aluminum, the columnar crystal structure of the ingot is less, the crystal grains are fine, and the forging ability is strong.
The addition of trace element Cu improves the plasticity of 6063 during hot working, and at the same time increases the heat treatment strengthening effect.
It has excellent welding performance, and the corrosion performance in the welding area remains unchanged.
It can be anodized, the color will not change after surface anodization. The anodizing appearance is very beautiful.
In terms of Mg and SI, 6061 is 30-50% more than 6063. The most direct effect is that 6061 has a greater strengthening effect than 6063.
The strengthening effect of 6061 heat treatment is greater. In contrast, the higher the tensile strength, the greater the deformation resistance, so the plasticity of the 6061 alloy is lower than 6063.
6061-T6 is used in occasions that require certain strength and hardness. 6063 is a representative alloy for extrusion with good extrudability.
Surface treatment: Both 6061 and 6063 anodizing properties are very good. 6063 aluminum is better.
Machinability: Both are good. 6061 is better.
Corrosion resistance: Both are good. 6063 is slightly better.
Weldability: 6063 is slightly better.
Price: 6063 aluminum sheet price is a little higher
Simply speaking, 6061’s advantage is strength, while 6063 wins in extrudability.
