)% rare earth elements were prepared by cold drawing and intermediate heat treatments. Microstructure was observed, and mechanical properties and electrical conductivity were measured for alloys at various drawing strain levels. Adding rare earth elements could reduce the size of primary Fe and Cu dendrites of Cu-6%Fe. Ultimate tensile strength increased but electrical conductivity decreased......
