Aluminum 5005 vs 5005A

Aluminum · grade comparison

Aluminum 5005 and 5005A are both aluminum grades. 5005A is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 138 MPa (20 ksi) for 5005, about 9% more. In exchange, 5005 is the more ductile: elongation 8% versus 6% for 5005A. 5005A runs hotter in service (150°C vs 120°C continuous). On the shop floor, 5005 sits in a lower cost tier (budget, $) than 5005A (standard, $$).

5005Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.

5005AChoose it when strength drives the design, or when the part sees heat.
