Aluminum 5056 vs 5652

Aluminum · grade comparison

Aluminum 5056 and 5652 are both aluminum grades, both corrosion resistant al. 5056 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 195 MPa (28.3 ksi) for 5652, about 21% more; tensile strength follows at 330 MPa (47.9 ksi) vs 230 MPa (33.4 ksi). 5056 is the more ductile: elongation 20% versus 12% for 5652, and 5056 is harder (78 HB vs 60 HB). 5652 runs hotter in service (150°C vs 65°C continuous) and 5652 conducts heat better (138 W/m·K vs 112 W/m·K). On the shop floor, 5652 sits in a lower cost tier (budget, $) than 5056 (standard, $$).

5056Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

5652Choose it when the part sees heat, or when cost is the deciding factor.
