Aluminum 8014 vs 8079

Aluminum · grade comparison

Aluminum 8014 and 8079 are both aluminum grades. 8014 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 35 MPa (5.08 ksi) for 8079, about 3.3 times as much; tensile strength follows at 140 MPa (20.3 ksi) vs 85 MPa (12.3 ksi). In exchange, 8079 is the more ductile: elongation 25% versus 6% for 8014, and 8014 is harder (42 HB vs 22 HB). 8079 conducts heat better (225 W/m·K vs 200 W/m·K). On the shop floor, 8079 sits in a lower cost tier (budget, $) than 8014 (standard, $$).

8014Choose it when strength drives the design.

8079Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
