Aluminum 5052 vs 5A03

Aluminum · grade comparison

Aluminum 5052 and 5A03 are both aluminum grades. 5052 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 90 MPa (13.1 ksi) for 5A03, about 117% more; tensile strength follows at 230 MPa (33.4 ksi) vs 200 MPa (29 ksi). In exchange, 5A03 is the more ductile: elongation 22% versus 12% for 5052, and 5052 is harder (60 HB vs 55 HB). 5052 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 5052 machines more easily (50 vs 40 out of 100) and 5052 sits in a lower cost tier (budget, $) than 5A03 (premium, $$$).

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

5A03Choose it when the part is bent, formed or impact-loaded.
