Gold Preforms
We offer wide selection of alloys and tooling options - let one of our metallurgists help you choose the best option.
WAMBRAZE™ Preforms
Williams develops preforms using a variety of alloys, including gold and other traditional brazing materials in temperature ranges from 487°C to 1240°C, suitable for almost every brazing application. Our manufacturing capabilities include designing and tooling up for higher volume parts, or utilizing our unique machining capabilities for lower volume or one off programs. Our current tool library includes discs, squares, rectangles, frames and washers in sizes from 0.010 - 5.000". Our tools are designed and built in-house and all machining is performed at Williams. |
