Aluminum 5005 vs 5A05

Aluminum · grade comparison

Aluminum 5005 and 5A05 are both aluminum grades. 5A05 is the stronger of the two: tensile strength 270 MPa (39.2 ksi) against 159 MPa (23.1 ksi) for 5005, about 70% more. 5A05 is the more ductile: elongation 22% versus 8% for 5005, and 5A05 is harder (70 HB vs 41 HB). 5005 runs hotter in service (120°C vs 65°C continuous) and 5005 conducts heat better (200 W/m·K vs 117 W/m·K). On the shop floor, 5005 sits in a lower cost tier (budget, $) than 5A05 (premium, $$$).

5005Choose it when the part sees heat, or when cost is the deciding factor.

5A05Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
