软化温度为550℃。

Abstract

Cu-0.8Cr-0.2Zr alloy containing Zr was prepared by internal oxidation method

and microstructure and properties of the alloy prepared were investigated.The experimental results indicate that the alloy maintains face centered cubic（FCC）lattice

and Zr-containing precipitates are dispersedly distributed in the matrix uniformly

so the alloy exhibits excellent performance.The hardness（HV）and the tensile strength of the alloy reach up to 141

430 MPa

respectively

while the electric conductivity reaches 43.5 MS/m with the softening temperature of 550 ℃.
