Aluminum 356 vs A535.0

Aluminum · grade comparison

Aluminum 356 and A535.0 are both aluminum grades. 356 is the stronger of the two: yield strength 186 MPa (27 ksi) against 125 MPa (18.1 ksi) for A535.0, about 49% more. In exchange, A535.0 is the more ductile: elongation 12% versus 5% for 356, and 356 is harder (80 HB vs 65 HB). 356 runs hotter in service (150°C vs 120°C continuous) and 356 conducts heat better (151 W/m·K vs 96 W/m·K). On the shop floor, A535.0 machines more easily (excellent vs very good) and 356 sits in a lower cost tier (budget, $) than A535.0 (premium, $$$).

356Choose it when strength drives the design, or when the part sees heat.

A535.0Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
