Aluminum 2319 vs 5183

Aluminum · grade comparison

Aluminum 2319 and 5183 are both aluminum grades. 5183 is the stronger of the two: yield strength 145 MPa (21 ksi) against 110 MPa (16 ksi) for 2319, about 32% more; tensile strength follows at 300 MPa (43.5 ksi) vs 200 MPa (29 ksi). 5183 is the more ductile: elongation 20% versus 16% for 2319, and 5183 is harder (80 HB vs 60 HB). 5183 is lighter (2.66 g/cm³ vs 2.84 g/cm³ for 2319) and 2319 runs hotter in service (175°C vs 65°C continuous). On the shop floor, 2319 machines more easily (good vs fair) and 5183 sits in a lower cost tier (standard, $$) than 2319 (premium, $$$).

2319Choose it when the part sees heat, or when the part is machined in volume.

5183Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
