摘要
The present invention provides a method of modifying conductivity- and strength-related properties of a Cu-Ag alloy plate produced by predetermined annealing and cold rolling, composed of 4 to 32% by atom of Ag and Cu accounting for the balance, wherein the plate rolled at any reduction ratio is heated at different temperature levels, and strength and conductivity of the plate after the annealing are measured for each annealing temperature so as to establish the conductivity-annealing temperature curve and strength-annealing temperature curve as the correlations between annealing temperature and strength and between annealing temperature and conductivity, then, an optimum annealing temperature required to provide a desired conductivity or strength is determined by extrapolating the above-described conductivity-annealing temperature curve or strength-annealing temperature curve at the desired conductivity or strength, and the plate prepared at any reduction ratio is annealed at the optimum annealing temperature.
