Information

Dispersion strengthened copper alloy is a kind of copper alloy widely used in industry. Compared with pure copper, it has high yield strength and tensile strength, and with the increase of temperature, it still has high strength, hardness and Conductivity. The dispersion-strengthened copper alloy is not easy to soften at high temperature, its softening temperature can be as high as 900 ℃ or more, and the conductivity can be as high as 85% IACS or more. These excellent characteristics make it widely used in the preparation of key materials such as electrical contacts, resistance welding electrode materials, gas shielded welding protection nozzles, cutting protection nozzles, and has important applications in welding, electronic communications, home appliances, automobiles and other fields.

Among the dispersion-strengthened copper alloys, copper-aluminum alloy (Cu-Al2O3) is the most widely used type of alloy. In addition, alloys with components such as copper zirconium and copper lanthanum also have important applications. The strengthening mechanism of dispersion-strengthened copper alloys lies in the introduction of one or more fine-sized and dispersed hard dots, such as alumina, zirconia, lanthanum oxide, etc., into the copper matrix through internal oxidation of the pre-alloyed powder. The material gains a strengthening effect.
