Aluminum 5005 vs 5070

Aluminum · grade comparison

Aluminum 5005 and 5070 are both aluminum grades. 5070 is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 138 MPa (20 ksi) for 5005, about 9% more; tensile strength follows at 290 MPa (42.1 ksi) vs 159 MPa (23.1 ksi). 5070 is the more ductile: elongation 17% versus 8% for 5005, and 5070 is harder (75 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 5070 (premium, $$$).

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

5070Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
