Brush Wellman Awarded U.S. Patent for Copper/Tungsten Composites.Business Editors TUCSON, Ariz.--(BUSINESS WIRE)--May 15, 2000 Brush Wellman Inc (NYSE NYSE See: New York Stock Exchange :BW), Powder Metal Products Group (a business unit of the Electronic Products Division) today announced that the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. Patent Office has awarded a patent to manufacture improved net shape or near net shape copper/tungsten products. Inventors of the process are David Jech, Director of Technology, Juan Sepulveda, Director of Technical Marketing, and Anthony Traversone, Process Engineering Specialist, all of Powder Metal Products Group. Net shape or near net shape parts are improved by sintering sintering, process of forming objects from a metal powder by heating the powder at a temperature below its melting point. In the production of small metal objects it is often not practical to cast them. a metal containing chemically bound oxygen compact in a well controlled moisture containing hydrogen atmosphere. Densification is aided by the formation of a transient metal-metal oxide eutectic during the sintering. "The new process offers greater efficiency and lower cost manufacturing of iron, copper and nickel based P/M P/M Powder Metallurgy P/M Pipe Major (director of bagpipe music in a Scottish pipeband) P/M Projectile/Mortar parts by eliminating the post-fired machining step" stated Ralph Hershberger, General Manager, Powder Metal Products Group. Copper/tungsten applications include microprocessors, microwave modules, wireless telecommunication devices and other power RF packages.
