Copper Alloy C36000-H02 vs C36000-M30

Copper Alloy · C36000 temper comparison

C36000-H02 and C36000-M30 are two conditions of the same copper alloy grade, C36000: H02 (half hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C36000-H02 is the stronger of the two: yield strength 310 MPa (45 ksi) against 125 MPa (18.1 ksi) for C36000-M30, about 148% more; tensile strength follows at 385 MPa (55.8 ksi) vs 340 MPa (49.3 ksi). In exchange, C36000-M30 is the more ductile: elongation 45% versus 22% for C36000-H02, and C36000-H02 is harder (115 HB vs 85 HB).
