What rare earth elements are mainly used in aluminum wires?

According to the introduction of some rare earth aluminum cable manufacturers on the Internet, such as Daming Cable Co., Ltd., the production technology of rare earth aluminum cable is imported from developed countries such as the United States and Canada (its aluminum cable technology is advanced and has been safely used for 46 years). According to the standard of American ASTM B800-05( 1 1), only the standard content requirements of boron, chromium, copper, iron, magnesium, silicon, zinc, titanium and other elements in aluminum cables are pointed out, and the rare earth element ~ rare earth aluminum cable technology is not involved. Under the innovative integration of cable technology experts in China, silver element and refined aluminum alloy are added. According to the test report of aluminum alloy conductor composition provided by Daming Rare Earth Aluminum Cable Company Cable Co., Ltd. on the Internet, lanthanum (La) and cerium (Ce) account for 0.09% of rare earth elements, while other rare earth elements such as praseodymium (Pr) and neodymium (nd) account for less than 0.0 1%. The above information is for your reference only, and I hope it will help you. For details, please consult the manufacturer of rare earth aluminum alloy bars.
