6061 aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. It has good formability, weldability and machinability. Features include formability, weldability, machinability and excellent plating properties. In addition, 6061 aluminum alloy also has the characteristics of good corrosion resistance, high toughness, not easy to deform, dense and defect-free material, and easy to polish and color.


Physical properties:

  1. Density: approximately 2.7 g/cm3.
  2. Young’s modulus: approximately 69 GPa (10,000 ksi).
  3. Electrical conductivity: Because it contains a small amount of copper, it can neutralize the adverse effects of iron on electrical conductivity.
  4. Thermal conductivity: approximately 152 W/m K.

Chemical properties:

  1. The main alloying elements are magnesium and silicon, forming the Mg2Si phase, which has medium strength, good corrosion resistance, weldability and good oxidation effect.
  2. The adverse effects of iron can be neutralized if certain amounts of manganese and chromium are included.
  3. Small amounts of copper or zinc are sometimes added to increase the strength of the alloy without significantly reducing its corrosion resistance.

In addition, 6061 aluminum alloy also has excellent oxidation effect, can be anodized and colored, and is suitable for use as building decoration materials. It contains a small amount of copper, which can neutralize the adverse effects of iron on conductivity. At the same time, zirconium or titanium can refine the grains and control the recrystallized structure, improving its cutting performance. In order to obtain higher strength, solution treatment and quenching aging are required.


  1. In aerospace, it is used for aircraft skins, fuselage frames, inner wall panels, rotors, propellers, fuel tanks, landing gear and other parts;
  2. In transportation, it is used to make subway cars, accessories, doors, windows, rails, car wall panels, wheels and engine parts, etc;
  3. In construction, it is used to make doors, windows, curtain walls and aluminium panels; it is also widely used in fields such as electronic equipment and sports equipment.
