| Abstract: | Wires of hyper-eutectic Cu-Cr alloy were cast by heated mold continuous casting process, and their microstructure, mechanical properties and electrical conductivity were investigated on as-cast. The results show that their tensile strength increases with increase of the Cr content, their electric conductivity become higher with increase of the casting speed. |
