Aluminum 6005A vs 6053

Aluminum · grade comparison

Aluminum 6005A and 6053 are both aluminum grades. 6005A is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 220 MPa (31.9 ksi) for 6053, about 7% more; tensile strength follows at 275 MPa (39.9 ksi) vs 255 MPa (37 ksi). In exchange, 6053 is the more ductile: elongation 13% versus 11% for 6005A, and 6005A is harder (95 HB vs 80 HB). On the shop floor, 6005A welds better (excellent vs very good) and 6005A sits in a lower cost tier (budget, $) than 6053 (premium, $$$).

6005AChoose it when strength drives the design, or when it will be welded.

6053Choose it when the part is bent, formed or impact-loaded.
