A New Method of Directional Solidification of Cu-Cr Alloy

In order to meet the need of high-strength and high-electrical conductivity copper alloys in industry. A method of making high-strength and high-electrical conductivity copper alloys is discussed in this paper. This method uses the technology of heated mold continuous casting to make Cu-Cr alloy. Because it utilizes the high electrical conductivity of copper matrix and high strength of the chromium phase, the in-situ composite Cu-Cr alloy with directional solidification structure is got. The in-situ composite Cu-Cr alloy has good properties and will be widely used in industry.
