Copper Alloy C73500-H02 vs C73500-H10

Copper Alloy · C73500 temper comparison

C73500-H02 and C73500-H10 are two conditions of the same copper alloy grade, C73500: H02 (half hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. C73500-H10 is the stronger of the two: yield strength 660 MPa (95.7 ksi) against 415 MPa (60.2 ksi) for C73500-H02, about 59% more; tensile strength follows at 725 MPa (105 ksi) vs 480 MPa (69.6 ksi). In exchange, C73500-H02 is the more ductile: elongation 10% versus 1.5% for C73500-H10, and C73500-H10 is harder (205 HB vs 130 HB). C73500-H02 runs hotter in service (175°C vs 150°C continuous). On the shop floor, C73500-H02 welds better (good vs fair).

C73500-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C73500-H10Choose it when strength drives the design.
