Copper Alloy C33500-H01 vs C33500-H02

Copper Alloy · C33500 temper comparison

C33500-H01 and C33500-H02 are two conditions of the same copper alloy grade, C33500: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C33500-H02 is the stronger of the two: yield strength 345 MPa (50 ksi) against 275 MPa (39.9 ksi) for C33500-H01, about 25% more; tensile strength follows at 420 MPa (60.9 ksi) vs 365 MPa (52.9 ksi). In exchange, C33500-H01 is the more ductile: elongation 43% versus 23% for C33500-H02, and C33500-H02 is harder (120 HB vs 100 HB).

C33500-H01Choose it when the part is bent, formed or impact-loaded.

C33500-H02Choose it when strength drives the design.
