Abstract
A comparison is made between FRHC firerefined highconductivity and ETP electrolytically tough pitch copper wire in colddrawn samples Conductivity and mechanical properties are evaluated as a function of the annealing temperature The firerefined copper samples with controlled amounts of impurities show the higher annealing temperatures needed to achieve the 1000 IACS International Annealed Copper Standard required to be an electrical conductor Nevertheless FRHC copper keeps its mechanical properties for a wider range of annealing temperatures than ETP copper thereby becoming an interesting alternative for some industrial applications such as trolley wire or fire detection systems The applicability as trolley wire is evaluated by comparing ETP copper with commercial grades and an electrical conductivitytensile strength chart for this application is presented
