Copper Alloy C17510 vs CuCrZr

Copper Alloy · grade comparison

Copper Alloy C17510 and CuCrZr are both copper alloy grades. CuCrZr is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 170 MPa (24.7 ksi) for C17510, about 106% more; tensile strength follows at 430 MPa (62.4 ksi) vs 310 MPa (45 ksi). In exchange, C17510 is the more ductile: elongation 25% versus 22% for CuCrZr, and CuCrZr is harder (130 HB vs 70 HB). CuCrZr runs hotter in service (450°C vs 200°C continuous) and CuCrZr conducts heat better (320 W/m·K vs 105 W/m·K). On the shop floor, CuCrZr machines more easily (fair vs poor) and CuCrZr sits in a lower cost tier (premium, $$$) than C17510 (specialty, $$$$$).

C17510Choose it when the part is bent, formed or impact-loaded.

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