Copper Alloy C67500-H02 vs C67500-O60

Copper Alloy · C67500 temper comparison

C67500-H02 and C67500-O60 are two conditions of the same copper alloy grade, C67500: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C67500-H02 is the stronger of the two: yield strength 310 MPa (45 ksi) against 207 MPa (30 ksi) for C67500-O60, about 50% more; tensile strength follows at 517 MPa (75 ksi) vs 448 MPa (65 ksi). In exchange, C67500-O60 is the more ductile: elongation 33% versus 20% for C67500-H02, and C67500-H02 is harder (160 HB vs 130 HB).

C67500-H02Choose it when strength drives the design.

C67500-O60Choose it when the part is bent, formed or impact-loaded.
