Copper Alloy C14500 vs C17465

Copper Alloy · grade comparison

Copper Alloy C14500 and C17465 are both copper alloy grades. C17465 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 275 MPa (39.9 ksi) for C14500, about 100% more; tensile strength follows at 690 MPa (100 ksi) vs 310 MPa (45 ksi). In exchange, C14500 is the more ductile: elongation 18% versus 15% for C17465, and C17465 is harder (195 HB vs 85 HB). C17465 is stiffer (138 GPa vs 117 GPa) and C17465 runs hotter in service (300°C vs 200°C continuous). On the shop floor, C14500 machines more easily (excellent vs good).

C14500Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

C17465Choose it when strength drives the design, or when the part sees heat.
