6082 is a heat-treatable, wrought aluminum alloy belonging to the Al-Mg-Si-Mn series (EN designation: AlSi1MgMn, 3.2315). It is one of the highest-strength alloys in the 6000 series and is widely used for industrial structural components in Europe and the United States.

Key characteristics: In the T6 temper, it offers higher strength than 6061; the addition of manganese (Mn) refines the grain structure, resulting in excellent fatigue resistance and resistance to stress-induced deformation. It features excellent weldability and machinability, as well as good atmospheric corrosion resistance. However, it is more difficult to extrude than 6061 or 6063, and its anodized finish is slightly inferior to that of 6063. It is suitable for heavy-duty structural components subject to sustained loads. Density: 2.70 g/cm³.

Common supply tempers:

T6 (most common): Solution heat treatment followed by water quenching and artificial aging; tensile strength ≥310 MPa, yield strength ≥260 MPa, elongation ≥8%, hardness approx. 95 HB.

T4: Solution heat treatment followed by natural aging; offers better ductility and is suitable for bending/forming, though strength is lower.

Chemical composition

Specifications

Product Types: Extruded aluminum tubes, seamless cold-drawn aluminum tubes; customizable in round, square, and rectangular profiles.

Surface Treatments: Natural anodizing, hard anodizing, powder coating, polishing, and brushing.

Export projects involving heavy-duty machinery frames typically utilize anodizing to balance corrosion resistance with aesthetic appeal.

Application Scenarios
