Aluminum 5050 vs 5A06

Aluminum · grade comparison

Aluminum 5050 and 5A06 are both aluminum grades. 5A06 is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 145 MPa (21 ksi) for 5050, about 14% more; tensile strength follows at 330 MPa (47.9 ksi) vs 170 MPa (24.7 ksi). 5A06 is the more ductile: elongation 20% versus 9% for 5050, and 5A06 is harder (70 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 117 W/m·K). On the shop floor, 5050 sits in a lower cost tier (budget, $) than 5A06 (premium, $$$).

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

5A06Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
