6061 (T6) aluminum alloy is a high-quality aluminum product created through a heat treatment and pre-stretching process. This alloy falls under the category of heat-treatable strengthening alloys, offering excellent formability, weldability, and machinability. It possesses medium strength and retains good operability after annealing. The primary alloying elements in 6061 aluminum are magnesium and silicon, which combine to form the Mg2Si phase. The addition of manganese and chromium can help neutralize the negative effects of iron, while small amounts of copper or zinc can enhance the alloy’s strength without significantly compromising its corrosion resistance. Copper can also mitigate the adverse effects of titanium and iron on electrical conductivity. Furthermore, zirconium or titanium can refine the grain structure and control recrystallization, while lead and bismuth may be added to improve machinability. The dissolution of Mg2Si in aluminum provides the alloy with artificial aging hardening capabilities.
Mechanical Properties:
Tensile Strength (σb): ≥ 290 MPa
Elongation Stress (σp0.2): ≥ 240 MPa
Elongation Rate: ≥ 10%
Note: These mechanical properties pertain to seamless rods with a specimen size of diameter ≥ 70 mm.
Heat Treatment Process:
Rapid Annealing: Heating temperature of 350-410°C; holding time varies from 30 to 120 minutes depending on the effective thickness of the material; cooled by air or water.
High-Temperature Annealing: Heating temperature of 350-500°C; for finished products with a thickness of ≥ 6 mm, holding time is 10-30 minutes; for thickness less than 6 mm, heat through air cooling.
Low-Temperature Annealing: Heating temperature of 150-250°C; holding time is 2-3 hours; cooled by air or water.
Homogenization: Conducted at 570°C with a holding time of 7 hours, followed by air cooling.
Additional Information:
The density of 6061 aluminum alloy is approximately 2800 kg/m³.
6061 aluminum alloy is widely used in various applications, including structural components, automotive parts, and aerospace applications, due to its favorable combination of strength and workability.
