METHOD FOR MANUFACTURING COPPER-SILVER ALLOY WIRE AND COPPER-SILVER ALLOY WIRE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a Cu-Ag alloy wire having high electrical conductivity and strength.;SOLUTION: The method for manufacturing a Cu-Ag alloy wire includes (1) a continuous casting step of producing a cast wire material having a diameter of 6 to 40 mm by continuously casting a Cu-Ag alloy having a composition containing 0.5-15 mass% of Ag, with the remainder comprising Cu and inevitable impurities, (2) a conform extrusion step of producing an extruded wire material having a diameter of 3-40 mm by subjecting the cast wire material to conform extrusion, and (3) a cold working step of producing the Cu-Ag alloy wire by applying cold working with an area reduction rate of 95% or more to the extruded wire material.;COPYRIGHT: (C)2015,JPO&INPIT
