Aluminum 6005 vs 6053

Aluminum · grade comparison

Aluminum 6005 and 6053 are both aluminum grades. 6005 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 220 MPa (31.9 ksi) for 6053, about 11% more; tensile strength follows at 270 MPa (39.2 ksi) vs 255 MPa (37 ksi). In exchange, 6053 is the more ductile: elongation 13% versus 11% for 6005, and 6005 is harder (85 HB vs 80 HB). On the shop floor, 6005 sits in a lower cost tier (standard, $$) than 6053 (premium, $$$).

6005Choose it when strength drives the design, or when cost is the deciding factor.

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