Title: Production of fine wire of high-strength high-conductivity copper alloy
Inventor: EGUCHI KAZUMASA
IPC: C22F1/08
Filed: 1990-04-27
Abstract: PURPOSE:To produce a fine wire of a high-strength and highconductivity copper alloy by subjecting a rough drawn wire of a copper alloy having a composition in which the total content of additive elements including Cr is regulated to a specific value to cold wiredrawing, applying heat treatment at the time when intermediate wire diameter is reached to precipitate Cr, and further carrying out cold wiredrawing until the final wire diameter is reached. CONSTITUTION:An ingot of a copper alloy having a composition in which the total content of additive elements including at least Cr and consisting of In, etc., other than Cr is formed into a rough drawn wire. This rough drawn wire is subjected to cold wiredrawing into a fine wire of final wire diameter. At this time, heat treatment is applied to the fine wire of copper alloy at the time when intermediate wire diameter is reached on the way to the fine wire of the final wire diameter to precipitate Cr. The intermediate wire diameter is decided so that the reduction of sectional area reaches >=5%, preferably >=90%, wherein the reduction of sectional area (%) is (1-final wire sectional area/intermediate wire sectional area) X100%. Further, it is preferable to perform the above intermediate heat treatment at about 300-600 deg.C for >= about 1hr. After this heat treatment, the fine intermediate copper alloy wire is subjected to cold wiredrawing into a fine wire of the final wire diameter, and this wire is further subjected, if necessary, to heat treatment to undergo the uniformization of quality. By this method, mechanical properties and electric conductivity can be improved, and the fine wire of high-strength and high-conductivity copper alloy can be obtained.
