6082 T6 Aluminium Plate

6082 is a medium-strength structural alloy and the strongest of the 6000 series in general structural use. Corrosion resistance, weldability, and machinability are why it is chosen for mechanical processing. A higher manganese addition is used to control grain structure and raise strength. In many structural jobs it has taken the place of 6061 sheet and plate.

The same alloy is already in the catalogue as 6082 bar, 6082 pipe, and 6082 extruded tube.

T6 and T651 stock is held from 4 mm to 200 mm thick, up to 1500 mm wide, and from 2000 mm to 6000 mm long. Larger plates are made up to 3800 mm wide and 250 mm thick.

Surface: mill finish, polished, hairline, brushed, sand blasted, anodized.

Chemical composition

T6 mechanical properties

Minimum values. Elongation is on 50 mm. A separate T651 strength table is not published with this stock list.

Density is 2.7 g/cm³.

What the temper is used for

The plate is forged, rolled, stretched, and stamped. It welds by gas-shielded, arc, and laser processes. Anodising and paint are both used on the surface. The face is expected to be smooth, without obvious bumps, scratches, oxidation, or corrosion.

Imperial stock, T6 and T651

Each thickness below is listed for both T6 and T651, in 4 ft × 8 ft, 4 ft × 12 ft, and 5 ft × 10 ft (48 × 96 in, 48 × 144 in, and 60 × 120 in).

Thickness runs from 0.125 in, then 0.25 in through 10.0 in in steps of 0.25 in: 0.125, 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.25, 2.5, 2.75, 3.0, 3.25, 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.25, 5.5, 5.75, 6.0, 6.25, 6.5, 6.75, 7.0, 7.25, 7.5, 7.75, 8.0, 8.25, 8.5, 8.75, 9.0, 9.25, 9.5, 9.75, 10.0 in.

Metric stock, T6 and T651

Each thickness is listed for both tempers in 1250 × 2500 mm and 1500 × 3000 mm.

The stated stock band continues to 200 mm even where a thickness is not in the table above. Send temper, thickness, and blank size with an enquiry for a size outside the list.
