Properties and Fabrication of Alumina Dispersion Strengthened Copper Alloy with High Softening Temperature
Cu-Al2O3 alloy combine both high electronic conductivity and high softening temperature.Cu- Al2O3 alloy was fabricated by internal oxidation and hot extrusion methods in the present investigation.Microstructure and properties of Cu- Al2O3 alloy was studied.The influence of preparation parameters,hot extrusion parameters and heat treatment on the properties of the alloy was investigated.The results indicated that the grain of the alloy was very small with a size between 2-10μm.Softening temperature of the Cu-0.6% Al2O3 alloy and Cu-1.0% Al2O3 alloy was 900℃.Cu-0.6%Al2O3 alloy and Cu-1.0% Al2O3 alloy meeting the requirements for electrode in resistance welding is the ideal substitution of the traditional electrode materials for resistance welding.
