Aluminum 296.0 vs 319

Aluminum · grade comparison

Aluminum 296.0 and 319 are both aluminum grades. 296.0 is the stronger of the two: yield strength 179 MPa (26 ksi) against 124 MPa (18 ksi) for 319, about 44% more; tensile strength follows at 275 MPa (39.9 ksi) vs 186 MPa (27 ksi). 296.0 is the more ductile: elongation 5% versus 2% for 319, and 296.0 is harder (95 HB vs 70 HB). 319 runs hotter in service (200°C vs 150°C continuous) and 296.0 conducts heat better (138 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 296.0 (standard, $$).

296.0Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

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