Previous studies have shown that various additives can greatly improve the properties of copper based electrodes. In this paper, the influence of Cr content changes and different pressing and sintering process parameters on mechanical and physical properties was investigated. The results showed that 2 vol.% Cu-Cr powder composite alloys prepared by pressing pressure 450 MPa and sintering temperature of 1100 °C had the optimal mechanical and physical properties, and its density, porosity, hardness and tensile strength were 8,35 g/cm 3 , 2%, 124 HB and 264 MPa, respectively. In addition, the hardness was increased by 5-7% compared with that of pure copper prepared by conventional casting method.

“…However, Ag and Nb are precious metal materials, which are difficult to be widely used in practical production. At the same time, at high temperatures the solubility of Fe is high and at low temperatures the precipitation from Cu is slow, therefore the electrical conductivities of Cu-Fe alloys are relatively low [4,5]. Cr has relatively low cost, high strength, and low solubility in the Cu matrix.…”

Copper has excellent electrical conductivity, but the disadvantages of low strength and hardness limit its application range. In this paper, Cu-XCr (X=5, 7, and 9, where 5, 7, and 9 are all mass percentages) alloys were treated as the object of study; the impacts of Cr contents on the microstructure, Vickers hardness, and conductivity of Cu-XCr alloys were investigated using an XHC-SV2 upright metallographic microscope, a digital display Vickers hardness tester, and a Sigma2008C digital metal conductivity meter; the optimal Cr content was determined by the comprehensive performance parameter Z. The research results showed that the second phase of Cu-XCr alloys contained dendritic, nearly spherical, and other shapes. The size was relatively small, and the distribution was relatively uniform; the Vickers hardness improved and the electrical conductivity declined with climbing Cr content; when X=7, the comprehensive performance parameter Z of Cu-XCr alloys reached a maximum of 6.7×105 HV2·%IACS.
