Aluminum 5049 vs 5050

Aluminum · grade comparison

Aluminum 5049 and 5050 are both aluminum grades. 5049 is the stronger of the two: tensile strength 240 MPa (34.8 ksi) against 170 MPa (24.7 ksi) for 5050, about 41% more. 5049 is the more ductile: elongation 11% versus 9% for 5050, and 5049 is harder (62 HB vs 46 HB). 5050 runs hotter in service (150°C vs 120°C continuous) and 5050 conducts heat better (191 W/m·K vs 138 W/m·K). On the shop floor, 5050 sits in a lower cost tier (budget, $) than 5049 (premium, $$$).

5049Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

5050Choose it when the part sees heat, or when cost is the deciding factor.
