Effect of Y on structure and properties of copper and its alloy

摘要：

The possibility of substituting 72.5Cu-22.7Zn-3.4Al brass for phosphorus bronze in some case that is now extensively used for elastic component,and purifying the scrap copper for recycling metal was investigated.By adding a little amount of rare earth Y into scrap copper and 72.5Cu-22.7Zn-3.4Al brass to research their structure and characteristics,especially the electric conductivity for scrap copper and HV for the brass were researched.The results show that the tensile strength,elongation and electric conductivity (IACS) of 0.38 mm strip of scrap copper with 0.04％ Y,are 213.8 MPa,23％ and 98.5％ that suit for the elastic components.The tensile strength,elongation and HV of 0.25mm strip of the brass with 0.03％ Y are 665.1MPa,2.86％ and 226 that satisfy the usage requirement for the elastic components.Meanwhile,the cost is cheaper than phosphorous bronze because of implying 22.7％ zinc in the brass,which has the actual application value.
