Mitsubishi Materials Develops High Performance Cu Alloy Wire

Mitsubishi Materials announced on Thursday the firm succeeded in making new copper alloy wire containing active element by continuous copper wire rod casting and rolling process. The new alloy wire shows high performance in strength, conductivity, heat resistance and flex resistance. With the process for copper-tin alloy and copper-silver alloy wires, nobody could make the alloy with active element. However, as the developer of the process, the firm finally developed the knowhow to make the product with enough long length and economically affordable cost by combining technology for oxygen free wire making and continuous copper alloy making.

Mitsubishi Materials expects the new copper alloy wire could be used for automotive electric cable. The firm emphasizes the wire can contribute to lower production cost for the users by reducing the cable size or weight when the property secures workability and credibility at the users’ process.

The firm also expects the new wire is used for trolley wire for high speed railway. The firm appeals the new wire has similar performance as the firm’s trolley wire products and the production cost is lower than the trolley wire.
