A treatment process is provided for a copper-beryllium alloy comprising from about 0.2% to about 0.7% beryllium, no greater than 3.5% of cobalt and/or nickel, no greater than 0.5% of titanium and/or zirconium and at least 90% copper, wherein the alloy has been cold worked to a ready-to-finish gauge, comprising the steps of annealing the cold worked ready-to-finish gauge copper-beryllium alloy at a temperature from about 1500 DEG F. to about 1685 DEG F., cold working the annealed copper-beryllium alloy to reduce its gauge to a range of from about 20% to about 60%, and age hardening the copper-beryllium alloy at a temperature of from about 700 DEG F. to about 950 DEG F. for about 1 to about 7 hours. The alloy is characterized by satisfactory levels of strength and electrical conductivity as well as enhanced levels of formability, particularly in the direction parallel to the direction of rolling the alloy.
