Copper Alloy C52100-H02 vs C52100-H04

Copper Alloy · C52100 temper comparison

C52100-H02 and C52100-H04 are two conditions of the same copper alloy grade, C52100: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C52100-H04 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 450 MPa (65.3 ksi) for C52100-H02, about 30% more; tensile strength follows at 660 MPa (95.7 ksi) vs 565 MPa (81.9 ksi). In exchange, C52100-H02 is the more ductile: elongation 28% versus 10% for C52100-H04, and C52100-H04 is harder (170 HB vs 147 HB).

C52100-H02Choose it when the part is bent, formed or impact-loaded.

C52100-H04Choose it when strength drives the design.
