6082 T6 Aluminum Round Bar

6082 T6 aluminum alloy is a high-strength heat-treated aluminum alloy belonging to the 6000 series. It is mainly composed of silicon and magnesium, offering a balance of strength, corrosion resistance, and machinability. The T6 condition indicates that the material has undergone solution heat treatment and artificial aging to achieve its mechanical properties.

6082-T6 belongs to the Al-Mg-Si series aluminum alloy, with magnesium (Mg) and silicon (Si) as its main alloying elements, and contains small amounts of copper (Cu), iron (Fe), manganese (Mn), chromium (Cr), and other trace elements to enhance comprehensive performance. Its density is approximately 2.7g/cm³. After T6 heat treatment (solution treatment + artificial aging), its strength is significantly improved to an upper-medium level while maintaining good ductility.

6082 T6 aluminum round bar is a high-strength structural alloy. Due to its balance of mechanical properties, corrosion resistance, and machinability, it is widely used in industrial and engineering applications.
