Copper Alloy C15760-H02 vs C15760-H04

Copper Alloy · C15760 temper comparison

C15760-H02 and C15760-H04 are two conditions of the same copper alloy grade, C15760: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C15760-H04 is the stronger of the two: yield strength 545 MPa (79 ksi) against 490 MPa (71.1 ksi) for C15760-H02, about 11% more; tensile strength follows at 600 MPa (87 ksi) vs 555 MPa (80.5 ksi). In exchange, C15760-H02 is the more ductile: elongation 14% versus 11% for C15760-H04, and C15760-H04 is harder (165 HB vs 152 HB).

C15760-H02Choose it when the part is bent, formed or impact-loaded.

C15760-H04Choose it when strength drives the design.
