Copper Alloy C17465-TD02 vs C17465-TH04

Copper Alloy · C17465 temper comparison

C17465-TD02 and C17465-TH04 are two conditions of the same copper alloy grade, C17465: TD02 (solution heat treated and cold worked, half hard) versus TH04 (TD04 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C17465-TH04 is the stronger of the two: yield strength 690 MPa (100 ksi) against 370 MPa (53.7 ksi) for C17465-TD02, about 86% more; tensile strength follows at 760 MPa (110 ksi) vs 450 MPa (65.3 ksi). In exchange, C17465-TD02 is the more ductile: elongation 12% versus 9% for C17465-TH04, and C17465-TH04 is harder (225 HB vs 130 HB). C17465-TH04 runs hotter in service (300°C vs 200°C continuous) and C17465-TH04 conducts heat better (220 W/m·K vs 135 W/m·K).
