Abstract

Highly conductive materials with high strength have been required for the development of high field magnets such as the pulsed magnet. Compared with Cu-Al₂O₃, Cu-Be, Cu-Cr and Cu-Nb alloys, Cu-Ag alloys are very useful because of easiness in melting and casting. In addition, the alloys exhibit high strength, high conductivity and uniform characteristics by the proper combination of cold-working and heat-treatment. We manufactured the Cu-Ag alloys conductor (4×6 mm in cross section). The conductor has a tensile strength of 1000 MPa and an electrical conductivity of 80% IACS at room temperature, and this conductor is suitable for the high field pulsed magnet. It is also easy to handle the conductor in making a coil with a diameter of about φ20 mm
