Aluminum 2319 vs ER4011

Aluminum · grade comparison

Aluminum 2319 and ER4011 are both aluminum grades. 2319 is the stronger of the two: yield strength 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for ER4011, about 10% more; tensile strength follows at 200 MPa (29 ksi) vs 185 MPa (26.8 ksi). 2319 is the more ductile: elongation 16% versus 6% for ER4011, and 2319 is harder (60 HB vs 55 HB). ER4011 is lighter (2.67 g/cm³ vs 2.84 g/cm³ for 2319) and 2319 runs hotter in service (175°C vs 150°C continuous). On the shop floor, 2319 machines more easily (good vs fair).

2319Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

ER4011Choose it when weight is the constraint.
