米乐yy易游体育 Steel licenses copper alloy for terminals and connectors to Germany's Wieland

November 19, 2012

TOKYO, November 19, 2012 - 米乐yy易游体育 Steel, Ltd. announces that it has licensed Germany's Wieland-Werke AG to produce and sell 米乐yy易游体育 Steel's CAC^TM5 copper alloy for terminals and connectors.

The license agreement with Wieland enables 米乐yy易游体育 Steel to establish a global supply network for copper alloys, especially for automotive applications. It also addresses the need for manufacturers to procure materials from multiple sources.

米乐yy易游体育 Steel had already licensed CAC^TM5 to Aurubis Buffalo Inc. in the United States in March 2008. The license to 米乐yy易游体育eland 米乐yy易游体育ll now enable CAC^TM5 to be supplied worldwide from Asia, the United States and Europe. The arrangement with Wieland is not a first. 米乐yy易游体育 Steel had previously provided Wieland with a license to make its SuperKFC^TM seri米乐yy易游体育 of copper alloys for semiconductor leadfram米乐yy易游体育.

米乐yy易游体育 Steel developed CAC^TM5, a high-米乐yy易游体育d product, in 2005 for use in automotive terminals and connections. CAC^TM5 is noted for its outstanding stress relaxation resistance and high strength. 米乐yy易游体育 Steel is working to establish CAC^TM5 as a next-g米乐yy易游体育eration world standard.

While CAC^TM5's chemical composition is Cu-Ni-Sn-P, it has about the same str米乐yy易游体育gth and b米乐yy易游体育ding formability as Cu-Ni-Si system alloys, which have many track records for use in small automotive terminals. CAC^TM5 is a low-cost copper alloy 米乐yy易游体育th outstanding stress relaxation resistance, which greatly contributes to reliability in terminals.

As automobiles become lighter and smaller and electrical components increase, terminals are becoming progressively smaller. With excellent stress relaxation resistance, high strength and low cost, 米乐yy易游体育 Steel anticipates that CAC^TM5 米乐yy易游体育ll be increasingly used.

A major European producer of copper rolled products, 米乐yy易游体育eland is the top supplier of copper alloys for automotive terminals and connectors in Europe.
