摘要 |
A method is provided for producing a wire or tape, especially for use as an electrode or electrode tip in spark plugs. The method includes the following steps: (a) producing an intermetallic compound having a melting point above 1700° C.; (b) grinding the intermetallic compound; (c) mixing the intermetallic compound with metal powder; (d) introducing the mixture obtained in step (c) in a tube produced from ductile material; and (e) shaping the tube filled in step (d) to give a wire or tape.
