Abstract
Saving copper by using aluminum is the international trend now, but the development is progress step by step and every country has a different processes. There is an obvious difference among China and other countries on the application of aluminum and aluminum alloy in electric cables. There is a wide development space for the aluminum alloy conductors using for overhead line. There is a little development for application of copper clad aluminum conductors and the related standards are being approved as well as written; we expect progressive test in use. Now we also expect to find good technic economic efficient means to separate the copper and aluminum during recycling processing. The market of aluminum clad steel wires is also expanding in recent years, with the maturity of manufacturing technology. The amount of aluminum enameled wire is also rising recently. It is no doubt that there is more fiber and less copper in the communication field continuously. There is a substantial progress of saving copper by using aluminum on airplanes. It is very important for saving energy and protecting environment through recycling copper and aluminum scrap directly. It is imperative under the situation to set up the recoverable networks of scrap wires of copper and aluminum.
