Brush Wellman's Williams Specialty Alloys Introduces Wambraze Powders for High Temperature Brazing.Business Editors BUFFALO, New York--(BUSINESS WIRE)--June 30, 2000 Williams Specialty Alloys, a division of Brush Wellman subsidiary Williams Advanced Materials, Buffalo, New York, has introduced its Wambraze(TM) high-temperature brazing brazing, method of joining metal parts using nonferrous filler metals with high melting points such as copper, silver, and aluminum alloys. Brazing differs from soldering (see solder) by using a higher temperature; and unlike welding, the parts are not melted. powders, which are designed for various applications including repairing jet engine turbine blades. "Wambraze(TM) powders are manufactured in a variety of alloys and temperature ranges to give our customers the powders necessary for optimal performance," said Joe Alfano, product manager, Williams Advanced Materials. "Each application requires a specific alloy and melt range and this is essential when dealing with the stresses and temperatures required in turbine operations." Williams Specialty Alloys employs the gas atomization Atomization The process whereby a bulk liquid is transformed into a multiplicity of small drops. This transformation, often called primary atomization, proceeds through the formation of disturbances on the surface of the bulk liquid, followed by their method to produce Wambraze(TM) powders. "Inert gases such as Argon argon (är`gŏn) [Gr.,=inert], gaseous chemical element; symbol Ar; at. no. 18; at. wt. 39.948; m.p. −189.2°C;; b.p. −185.7°C;; density 1.784 grams per liter at STP; valence 0. are used when the oxygen content must be kept low or when atomizing reactive metals," Alfano explained. "This allows for a cleaner environment and subsequently cleaner, oxide free-powders." To limit powder contamination in the tank where the process occurs, all internal surfaces of the chambers are fabricated from polished stainless steel and all seams are welded and polished. Among the alloys used in the process are gold/nickel, silver/copper, and gold/copper. Serving a wide variety of markets from electron tube to aerospace, Williams Advanced Materials has become a leader in the supply of high purity alloys.
