Aluminum 319 vs 713.0

Aluminum · grade comparison

Aluminum 319 and 713.0 are both aluminum grades. 713.0 is the stronger of the two: yield strength 152 MPa (22 ksi) against 124 MPa (18 ksi) for 319, about 23% more; tensile strength follows at 210 MPa (30.5 ksi) vs 186 MPa (27 ksi). 713.0 is the more ductile: elongation 4% versus 2% for 319, and 713.0 is harder (75 HB vs 70 HB). 319 runs hotter in service (200°C vs 150°C continuous) and 713.0 conducts heat better (140 W/m·K vs 109 W/m·K). On the shop floor, 319 welds better (good vs fair) and 319 sits in a lower cost tier (budget, $) than 713.0 (standard, $$).

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

713.0Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
