Aluminum 5050 vs 5654

Aluminum · grade comparison

Aluminum 5050 and 5654 are both aluminum grades. 5050 is the stronger of the two: yield strength 145 MPa (21 ksi) against 115 MPa (16.7 ksi) for 5654, about 26% more. In exchange, 5654 is the more ductile: elongation 25% versus 9% for 5050, and 5654 is harder (58 HB vs 46 HB). 5050 runs hotter in service (150°C vs 65°C continuous) and 5050 conducts heat better (191 W/m·K vs 126 W/m·K). On the shop floor, 5050 sits in a lower cost tier (budget, $) than 5654 (premium, $$$).

5050Choose it when strength drives the design, or when the part sees heat.

5654Choose it when the part is bent, formed or impact-loaded.
