Copper Alloy C19100-M11 vs C19100-TF00

Copper Alloy · C19100 temper comparison

C19100-M11 and C19100-TF00 are two conditions of the same copper alloy grade, C19100: M11 (as forged and quenched) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C19100-TF00 is the stronger of the two: yield strength 400 MPa (58 ksi) against 140 MPa (20.3 ksi) for C19100-M11, about 186% more; tensile strength follows at 470 MPa (68.2 ksi) vs 310 MPa (45 ksi). In exchange, C19100-M11 is the more ductile: elongation 35% versus 15% for C19100-TF00, and C19100-TF00 is harder (140 HB vs 72 HB). C19100-TF00 runs hotter in service (300°C vs 200°C continuous) and C19100-TF00 conducts heat better (180 W/m·K vs 150 W/m·K).

C19100-M11Choose it when the part is bent, formed or impact-loaded.

C19100-TF00Choose it when strength drives the design, or when the part sees heat.
