Microsecond high density electric pulse was used to shortly age Cu-2.5Fe-0.03P-0.1Zn copper alloy.The effects of electric pulse aging on the microstructures,electric conductivity and microhardness of this copper alloy were systematically investigated. The experimental results had shown that the alloy phase precipitated in Cu-2.5Fe-0.03P-0.1Zn alloy during electric pulse aging could be controlled to the order of fine nano-size and the ideal match of electric conductivity and microhardness could be achieved in the condition of optimized parameters of electric pulse.
