Aluminum 5052 vs 5070

Aluminum · grade comparison

Aluminum 5052 and 5070 are both aluminum grades. 5052 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 150 MPa (21.8 ksi) for 5070, about 30% more. In exchange, 5070 is the more ductile: elongation 17% versus 12% for 5052, and 5070 is harder (75 HB vs 60 HB). 5052 runs hotter in service (150°C vs 65°C continuous) and 5052 conducts heat better (138 W/m·K vs 117 W/m·K). On the shop floor, 5052 sits in a lower cost tier (budget, $) than 5070 (premium, $$$).

5052Choose it when strength drives the design, or when the part sees heat.

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