Copper Alloy C17300-TD04 vs C17300-TH01

Copper Alloy · C17300 temper comparison

C17300-TD04 and C17300-TH01 are two conditions of the same copper alloy grade, C17300: TD04 (solution heat treated and cold worked, full hard) versus TH01 (TD01 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17300-TH01 is the stronger of the two: yield strength 1,105 MPa (160 ksi) against 660 MPa (95.7 ksi) for C17300-TD04, about 67% more; tensile strength follows at 1,240 MPa (180 ksi) vs 760 MPa (110 ksi). In exchange, C17300-TD04 is the more ductile: elongation 6% versus 4% for C17300-TH01, and C17300-TH01 is harder (375 HB vs 230 HB). C17300-TH01 runs hotter in service (200°C vs 100°C continuous) and C17300-TH01 conducts heat better (130 W/m·K vs 105 W/m·K).

C17300-TD04Choose it when the part is bent, formed or impact-loaded.

C17300-TH01Choose it when strength drives the design, or when the part sees heat.
