More Information
Summary:The invention discloses copper alloy for manufacturing a mould and a preparation method thereof. The copper alloy consists of the following components in percentage by mass: 1.10 to 1.70 percent of Ni, 0.20 to 0.40 percent of Co, 0.10 to 0.40 percent of Be, 0.08 to 0.20 percent of Zr, 0.02 to 0.10 percent of Y, 0.02 to 0.05 percent of Ce, and the balance of Cu; and the copper alloy is prepared by processing steps of melting, pouring, hot forging, solid solution, cold forging and ageing. The copper alloy for manufacturing the mould has the characteristics of high strength and high thermal conductivity, and can also be used for welded joint discs and the like used on spot-welding electrodes and stainless steel besides being used for manufacturing injection moulds and nonferrous metal low-pressure die casting moulds with high thermal conductivity.
