EN AW-6082

Product Description

Aluminium alloy 6082 is one of the most widely specified alloys in the 6000-series. Characterised by magnesium and silicon additions, it is heat-treatable to high strength, delivering an excellent balance of strength, corrosion resistance, and machinability. Stress-relieved stock provides improved dimensional stability during deep machining.

Key Characteristics

• High strength with good corrosion resistance
• Very good machinability — recommended general-purpose CNC grade
• Good weldability (MIG and TIG)
• Heat-treatable
• Anodises well — natural and hard (Type III)

Machining Notes

Excellent machinability; recommended default CNC grade for structural applications. Carbide tooling at medium-to-high speeds with coolant. Suitable for tapping M3 and above. Stress-relieved stock minimises distortion during deep pocketing.

Typical Applications

Structural frames, transport equipment, aerospace secondary structures, mould tooling, hydraulic manifolds, machine parts, heavily loaded components, anodised enclosures.
