Aluminum 319 vs B535.0

Aluminum · grade comparison

Aluminum 319 and B535.0 are both aluminum grades. B535.0 is the stronger of the two: tensile strength 255 MPa (37 ksi) against 186 MPa (27 ksi) for 319, about 37% more. B535.0 is the more ductile: elongation 9% versus 2% for 319, and 319 is harder (70 HB vs 65 HB). B535.0 is lighter (2.62 g/cm³ vs 2.79 g/cm³ for 319) and 319 is stiffer (74 GPa vs 70 GPa). On the shop floor, B535.0 machines more easily (excellent vs very good), B535.0 welds better (very good vs good), and 319 sits in a lower cost tier (budget, $) than B535.0 (standard, $$).

319Choose it when the part sees heat, or when cost is the deciding factor.

B535.0Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
