HIGH-STRENGTH HIGH-CONDUCTIVE COPPER WIRE

A high strength and high conductivity copper rod or wire includes Co of 0.12 to 0.32 mass%, P of 0.042 to 0.095 mass%, Sn of 0.005 to 0.70 mass%, and O of 0.00005 to 0.0050 mass%. A relationship of 3.0 ‰¤ ([Co]-0.007)/([P]-0.008) ‰¤ 6.2 is satisfied between a content [Co] mass% of Co and a content [...

Beschreibung
Zusammenfassung:	A high strength and high conductivity copper rod or wire includes Co of 0.12 to 0.32 mass%, P of 0.042 to 0.095 mass%, Sn of 0.005 to 0.70 mass%, and O of 0.00005 to 0.0050 mass%. A relationship of 3.0 ‰¤ ([Co]-0.007)/([P]-0.008) ‰¤ 6.2 is satisfied between a content [Co] mass% of Co and a content [P] mass% of P. The remainder includes Cu and inevitable impurities, and the rod or wire is produced by a process including a continuous casting and rolling process. Strength and conductivity of the high strength and high conductivity copper rod or wire are improved by uniform precipitation of a compound of Co and P and by solid solution of Sn. The high strength and high conductivity copper rod or wire is produced by the continuous casting and rolling process, and thus production costs are reduced.
