Embodiment

[0023] A copper-cobalt alloy for electrodes with high electrical conductivity, each component is formulated according to the following weight percentages:

[0024] 0.5%Be;

[0025] 2%Co;

[0026] 1%Ni;

[0027] 0.3% Zr;

[0028] The balance is Cu.

[0029] The preparation method is as follows:

Abstract

The invention provides a high-conductivity copper-cobalt alloy for an electrode and a preparation method of the high-conductivity copper-cobalt alloy. The high-conductivity copper-cobalt alloy comprises, by weight, 0.1%-1% of Be, 1.2%-2.8% of Co, 0.5%-1.7% of Ni, 0.1%-0.5% of Zr and the balance Cu. The preparation method comprises the following steps that S1, burdening is conducted according to the weight percentage of all the components, S2, the temperature of a smelting furnace is increased to a certain temperature, Be, Co, Ni and Zr are added, S3, the temperature of the smelting furnace continues to be increased to a certain temperature, Cu is added, and alloy liquid is obtained after smelting is completed. Through the mutual strengthening effect between the alloys, the conductivity of the copper-cobalt alloy is improved. And meanwhile, through strict performance detection, the copper-cobalt alloy has good conductive performance and relatively high mechanical performance, room-temperature performance, high-temperature performance and wear resistance.

Description

technical field [0001] The invention relates to the field of manufacturing a copper-cobalt alloy for electrodes, in particular to a high-conductivity copper-cobalt alloy for electrodes and a preparation method thereof. Background technique [0002] As a metal material with electrical and thermal conductivity, pure copper has a density of about 8.9g / cm3 and a melting point of 1083°C. It not only has excellent thermal and electrical conductivity in terms of physical properties, but also has good ductility. It also has good corrosion resistance, but the strength of pure copper is relatively low. In order to meet the comprehensive requirements for material strength and electrical conductivity in practical applications, copper needs to be strengthened. Copper alloy is an alloy composed of pure copper as the base and adding one or several other elements. Copper alloys are widely used in fields such as electric power, heat dissipation, piping, and decoration because of their good ...
