Oxide Dispersion Strengthened Copper Alloy (ODSC) is a new high strength and high conductivity copper alloys. Nano-oxide particles enhanced the role both the improved high-temperature strength and hardness of the material, and also not significantly reduce the conductive properties of the alloy. Therefore, the material has good overall performance. ODSC (oxide dispersion strengthened copper) is used in the fabrication of resistance welding electrodes, seam welding wheel, welding torch nozzles, electrical switches touch the bridge, generator collector ring, armature, rotor, continuous casting machine mold liner, integrated circuit lead frame, trams and electric trains overhead the fine wire and other materials.
