ABSTRACT:
A method for enhancing the strength and hardness properties of a starting copper alloy having a matrix structure which has been cold worked and heat treated. The method includes the step of additional cold working followed by additional heat treating to increase the strength of the alloy without significantly affecting the electrical conductivity of the alloy. The method produces a strong and highly conductive material suitable for use as a field magnet which must experience high operational stress while carrying large current loads. The starting alloy may be a copper-beryllium-nickel alloy.
