Aluminum 2017A vs 2195

Aluminum · grade comparison

Aluminum 2017A and 2195 are both aluminum grades. 2195 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 260 MPa (37.7 ksi) for 2017A, about 112% more; tensile strength follows at 590 MPa (85.6 ksi) vs 410 MPa (59.5 ksi). In exchange, 2017A is the more ductile: elongation 14% versus 9% for 2195, and 2195 is harder (160 HB vs 110 HB). 2195 runs hotter in service (150°C vs 120°C continuous) and 2017A conducts heat better (134 W/m·K vs 115 W/m·K). On the shop floor, 2017A machines more easily (very good vs good), 2195 welds better (good vs poor), and 2017A sits in a lower cost tier (premium, $$$) than 2195 (high, $$$$).

2017AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

2195Choose it when strength drives the design, or when the part sees heat.
