Copper Alloy C41500-H02 vs C41500-H08

Copper Alloy · C41500 temper comparison

C41500-H02 and C41500-H08 are two conditions of the same copper alloy grade, C41500: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C41500-H08 is the stronger of the two: yield strength 586 MPa (85 ksi) against 400 MPa (58 ksi) for C41500-H02, about 47% more; tensile strength follows at 627 MPa (90.9 ksi) vs 455 MPa (66 ksi). In exchange, C41500-H02 is the more ductile: elongation 12% versus 2% for C41500-H08, and C41500-H08 is harder (195 HV vs 135 HV). C41500-H02 runs hotter in service (150°C vs 130°C continuous).

C41500-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C41500-H08Choose it when strength drives the design.
