C15760 is primarily used for applications requiring high temperature, high strength, and relatively high electrical and thermal conductivity. It exhibits strong resistance to softening at high temperatures.
C15760 features adequate cold working properties, suitable for mining, extrusion, and some stretching and rolling operations.
The softening temperature reaches up to 930°C, which is relatively high among copper alloys but lower than that of tungsten copper (1000°C), with a conductivity of up to 85% IACS.
Thermal conductivity ranges between tungsten copper (220 W/M.K) and pure copper (390 W/m-K).
Hardness exceeds HRB 84, with high strength, fatigue resistance, and good wear resistance.
Alumina copper dispersion strengthened CuAl2O3 composite material is a copper matrix reinforced with ultra-fine 12-25 nm Al2O3 particles, providing the material with high strength, hardness, conductivity, and high softening temperature. The production process includes: internal oxidation of Cu-Al alloy, isostatic pressing, sintering, hot extrusion, drawing, and processing into shape. It exhibits excellent thermal stability and good plasticity and workability.
