6082 Aluminum Plate/Sheet

Grade: 6082

Coil: 0.3mm-3.0mm

Sheet: 0.3mm-300mm

Width: 50mm-2000mm

Standard: ASTM, AMS, BS etc.

6082 is a heat-treatable aluminum magnesium silicon manganese alloy commonly selected for structural and machined plate in European engineering markets. Manganese helps control the grain structure, while solution treatment and artificial aging develop useful strength. T6 and stretch stress relieved T651 are common plate conditions. The alloy offers good corrosion resistance, machinability and weldability, although welding reduces local strength. Typical uses include transport structures, machinery components and load carrying assemblies where weight reduction is important.
