Aluminum 5052 vs 5A12

Aluminum · grade comparison

Aluminum 5052 and 5A12 are both aluminum grades. 5A12 is the stronger of the two: yield strength 210 MPa (30.5 ksi) against 195 MPa (28.3 ksi) for 5052, about 8% more; tensile strength follows at 400 MPa (58 ksi) vs 230 MPa (33.4 ksi). 5A12 is the more ductile: elongation 18% versus 12% for 5052, and 5A12 is harder (95 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 105 W/m·K). On the shop floor, 5052 welds better (excellent vs very good) and 5052 sits in a lower cost tier (budget, $) than 5A12 (premium, $$$).

5052Choose it when the part sees heat, or when it will be welded.

5A12Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
