Method of producing Cu - Ag alloy based conductive material
摘要
A method for producing a Cu-Ag alloy based conductive material containing about 10% to about 20% at % Ag, that involves the steps of continuously casting the alloy into a rod followed by quickly cooling the rod, cold-working the rod to a reduction in area of 80% or more, then heat treating the cold-worked rod at a temperature of 250 DEG C. to 350 DEG C. for 1 hour or more to form a heat-treated rod, and thereafter cold-working the heat-treated rod to a reduction in area of 90% or more as defined based on the cast rod to produce conductive material having a high strength of 700 MPa or more and conductivity of 75% IACA or more.
