Abstract: CuCr50 contact materials were prepared by three kind of processes,electrical arc melting, laser surface remelting and mechanical grinding powder then sintering. The microstructures and properties of the materials were also investigated. The results show that Cr grains were fined in the CuCr50 contact materials produced by above three methods. The size of Cr particles was much smaller than original ones, especially by laser surface remelting, the size of Cr particles is about 3~5 μm. In the view of oxygen contained, hardness and conductivity, laser surface remelting is the best way for producing fine grain contact materials. The best microstructure and properties can be abtained when the laser output is 3.2kW.
