A method for forming supports for use in electronic components. A plate of copper-based alloy including from 0.1 to 1.0% by weight nickel, and from 0.005 to 0.1% by weight of phosphorus is melted and cast. The alloy includes fine precipitates of nickel phosphides throughout the copper matrix. The plate is subjected to a series of deformation operations including, rolling and intermediate annealing at a temperature in the range of 400 DEG to 600 DEG C., with the annealing temperature being maintained for two to four hours, thereby maximizing the production of fine precipitates of nickel phosphides within the alloy. After alloy formation, the plate is coated with a layer of nickel, cut into a desired shape, and secured to an electronic component. |
