Aluminum 6005A vs 6082

Aluminum · grade comparison

Aluminum 6005A and 6082 are both aluminum grades. 6082 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 235 MPa (34.1 ksi) for 6005A, about 13% more; tensile strength follows at 310 MPa (45 ksi) vs 275 MPa (39.9 ksi). 6005A conducts heat better (190 W/m·K vs 170 W/m·K). On the shop floor, 6005A welds better (excellent vs very good) and 6005A sits in a lower cost tier (budget, $) than 6082 (standard, $$).

6005AChoose it when it will be welded, or when cost is the deciding factor.

6082Choose it when strength drives the design.
