Manufactured Process of High Strength and High Electrical Conductivity Cu-Cr-Zr-Mg Alloy Bars

Article Preview

Abstract:

A typical process was developed to manufacture Cu-Cr-Zr-Mg alloy bars with high strength and high electrical conductivity. The microstructure and properties of the alloys were investigated by observations of optical microscopy and scanning electron microscopy, and measurements of tensile strength and electrical conductivity. The results showed that the process and thermo mechanical treatments were successfully developed to manufacture Cu-Cr-Zr-Mg alloy bars with good combinations of the ultimate tensile strength (602.5 MPa) and conductivity (85.4% IACS). The achievement of high strength and high electrical conductivity in the alloy could be ascribed to the interactions of strain hardening and precipitation hardening.
