METHOD FOR MANUFACTURING PHOSPHORUS-CONTAINING COPPER ANODE MATERIAL FOR PLATING, WHICH COMPRISES UNIFORMLY DISPERSED PHOSPHORUS COMPONENT AND HAS FINE, UNIFORM CRYSTAL STRUCTURE, AND THE PHOSPHORUS-CONTAINING COPPER ANODE MATERIAL FOR PLATING

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a phosphorus-containing copper anode material for plating, which is suitably used as an anode material for plating, comprises a uniformly dispersed phosphorus component and has a fine, uniform crystal structure, and the phosphorus-containing copper anode material for plating manufactured thereby.

SOLUTION: The phosphorus-containing copper anode material for plating wherein the phosphorus component is uniformly dispersed and the crystal structure is fine and uniform is obtained by: repeating deep-drawing and forging of a phosphorus-containing copper ingot by repeating multiaxial compression and drawing at least once at an initial temperature of 600-900°C; subsequently performing hot- or cold-working at an initial temperature of ≤550°C; and, if necessary, further performing stress-relief annealing at a temperature ranging from 300 to 500°C, provided that the phosphorus-containing copper ingot has a Cu purity of ≥99.99 mass% and comprises 300-1,000 mass ppm P and ≤10 mass ppm oxygen.
