Aluminium 6082 T6 Sheet
6082-T6 aluminum sheet is a heat-treatable aluminum alloy with magnesium and silicon as its main alloying elements. It combines medium strength with excellent processing performance and is widely used in mechanical manufacturing and structural engineering fields.
T6 aluminum alloy is a heat-treatable forged alloy in the 6xxx series, characterized by a balanced combination of strength, corrosion resistance, and formability, making it a preferred sheet material for structural and high-stress applications.
When in the T6 temper, 6082 aluminum alloy undergoes solution heat treatment and artificial aging. It has a minimum yield strength of 260 MPa, a tensile strength of 310 MPa, while maintaining good ductility (elongation ≥ 8%) and machinability.
Its chemical composition mainly consists of aluminum, with 0.7–1.3% silicon, 0.6–1.2% magnesium, and up to 1% manganese, forming a fine-grained microstructure that provides good corrosion resistance in both atmospheric and marine environments.
6082 T6 is widely used in sheet thicknesses from 0.4 mm to 6 mm (and thick plates up to 12.5 mm in thickness), and is extensively applied in transportation frames, bridges, trusses, ship components, beer barrels, and general machining billets. This alloy complies with EN 485-2, EN 573-3, EN 754-2, and ISO 6361 standards, and can be easily welded, anodized, and formed using conventional processes.
