PURPOSE:To obtain a Cu alloy with superior strength, electric conductivity and bendability without requiring any heat treatment by adding specified very small amounts of Fe and B to Cu. CONSTITUTION:Cu is melted in a high frequency melting furnace, and after sealing the surface of the molten Cu with charcoal powder, Fe and B are added so that 0.05-0.1% Fe and 0.01-0.03% B are contained in 3.3-5.0 ratio of Fe/B. They are alloyed with the molten Cu, and the resulting alloy is worked into a wire rod by hot rolling and cold working. A Cu alloy wire rod for electric conduction with superior tensile strength, electric conductivity and bendability is obtd.
