Aluminum 319 vs 514.0

Aluminum · grade comparison

Aluminum 319 and 514.0 are both aluminum grades. 319 is the stronger of the two: yield strength 124 MPa (18 ksi) against 85 MPa (12.3 ksi) for 514.0, about 46% more; tensile strength follows at 186 MPa (27 ksi) vs 170 MPa (24.7 ksi). In exchange, 514.0 is the more ductile: elongation 9% versus 2% for 319, and 319 is harder (70 HB vs 50 HB). 514.0 is lighter (2.65 g/cm³ vs 2.79 g/cm³ for 319) and 319 runs hotter in service (200°C vs 120°C continuous). On the shop floor, 514.0 welds better (very good vs good) and 319 sits in a lower cost tier (budget, $) than 514.0 (standard, $$).

319Choose it when strength drives the design, or when the part sees heat.

514.0Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
