Extruded Aluminum rod bar 6082 T6 T651

6082 aluminum alloy is a medium-strength Al-Mg-Si alloy known for its excellent balance of strength, corrosion resistance, and machinability. Among its tempers, T6 and T651 are the most commonly specified for structural and precision applications.

Mechanical Properties of 6082 aluminum t6 t651

Heat Treatment & Stress Relief Process

T6 Temper

• Solution heat treated

• Artificially aged

• No stress relief process applied

• Results in:

• High strength

• Higher residual internal stress

• Greater risk of deformation during heavy machining

T651 Temper

• Based on full T6 heat treatment

• Followed by 1%–3% controlled cold stretching

• Benefits:

• Relieves approximately 80% of residual internal stress

• Enhances dimensional stability

• Reduces warping and distortion after machining

Machinability of 6082 aluminum 

6082-T6

• Suitable for general machining operations

• Larger allowable machining tolerances

• More prone to deformation after material removal

• Recommended when:

• Precision requirements are moderate

• Welding or further forming is involved

6082-T651

• Excellent machinability for precision parts

• Strong resistance to machining-induced deformation

• Maintains flatness and straightness after heavy cutting

• Preferred for:

• CNC machining

• Tight-tolerance components

• Multi-axis or deep-cut machining
