Abstract

The invention discloses a high-conductivity copper alloy and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing and smelting electrolytic copper, acopper molybdenum intermediate alloy and a nickel cerium intermediate alloy according to molar percentage, melting the prepared raw materials in a vacuum induction furnace, and controlling the vacuumdegree and the temperature in the smelting process, so as to obtain the high-conductivity copper alloy with both high conductivity and good mechanical properties. Compared with other conductive copperalloys, the high-conductivity copper alloy disclosed by the invention is capable of separating a nickel cerium intermediate phase with high conductivity, good mechanical properties and appropriate nano sizes at crystal boundaries, the mechanical properties of the copper alloy are maintained, moreover, the conductivity is improved. Therefore, the alloy has high conductivity and good mechanical properties, and the use range of the alloy is greatly widened.

Description

technical field [0001] The invention belongs to the technical field of high-performance copper alloys, in particular to a high-conductivity copper alloy and a preparation method thereof. Background technique [0002] Copper is the earliest non-ferrous metal discovered and closely related to human survival and social production. In the relevant records of early human society, there are people mining copper ore, smelting copper metal and using it to make daily utensils and various weapons. According to historical records, the discovery and use of copper has brought great progress to the development of human society. Pure copper, as a metal material with excellent electrical and thermal conductivity and excellent ductility, has been used until now. Its density is about 8.9g / cm3 and its melting point is as high as 1083°C. Pure copper and some copper alloys also have good corrosion resistance. Its chemical properties are very stable in dry air, but a basic copper carbonate subst...
