  • Patent number: 3947348
    Abstract: A method of making a wave guide by electrolytically depositing copper on a mandrel is improved by using, e.g., a nickel steel mandrel having a thermal coefficient of expansion about one-tenth or less of that of copper. After plating, the assembly is heated so that the copper tube separates from the mandrel without sticking, and can be taken off without exercise of undue force, which could damage mandrel or tube.
