Aluminum 5183 vs ER2519

Aluminum · grade comparison

Aluminum 5183 and ER2519 are both aluminum grades. ER2519 is the stronger of the two: yield strength 165 MPa (23.9 ksi) against 145 MPa (21 ksi) for 5183, about 14% more. In exchange, 5183 is the more ductile: elongation 20% versus 7% for ER2519. 5183 is lighter (2.66 g/cm³ vs 2.82 g/cm³ for ER2519) and ER2519 runs hotter in service (150°C vs 65°C continuous). On the shop floor, ER2519 machines more easily (good vs fair), 5183 welds better (excellent vs good), and 5183 sits in a lower cost tier (standard, $$) than ER2519 (high, $$$$).

5183Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

ER2519Choose it when strength drives the design, or when the part sees heat.
