Aluminum 319 vs 711.0

Aluminum · grade comparison

Aluminum 319 and 711.0 are both aluminum grades. 711.0 is the stronger of the two: yield strength 170 MPa (24.7 ksi) against 124 MPa (18 ksi) for 319, about 37% more; tensile strength follows at 240 MPa (34.8 ksi) vs 186 MPa (27 ksi). 711.0 is the more ductile: elongation 7% versus 2% for 319. 319 runs hotter in service (200°C vs 150°C continuous) and 711.0 conducts heat better (140 W/m·K vs 109 W/m·K). On the shop floor, 319 welds better (good vs poor) and 319 sits in a lower cost tier (budget, $) than 711.0 (premium, $$$).

319Choose it when the part sees heat, or when it will be welded.

711.0Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
