ABSTRACT:
A method is described for forming contacts which find use in vacuum interrupters. The method comprises making melt of a first metal having a high electrical conductivity and adding to the melt a second metal having a melting point in excess of the first metal and solubility in the first metal of less than 1 percent at the temperature to which the first metal is heated, intermixing the components to a uniform consistency casting the components to the desired configuration and thereafter cooling to room temperature.
