【Abstract】 The present paper describes the effects of chemical compositions of Cu—W alloys, particle sizes of tungsten powder and its distribution, macrohardness,densities, microstructure and defects etc, on the properties of P/M copper-tungsten alloy contactors. The analyses of microstructure is one of the important methods for controlling and evaluating the qualities of copper-tungsten alloy contactors。更多还原
