Brazing tungsten carbide - Part 2: Brazing filler materials and fluxes for use with tungsten carbide

The most popular families of alloys for the brazing of tungsten carbide are those that contain silver. Such materials have the benefit of low working temperatures, excellent wetting characteristics, high shear and tensile strength and, depending on their composition, outstanding fatigue properties. In addition, they are readily available in the form of rod, wire, strip, foil (with and without an interlayer of copper, a copper-nickel alloy or a woven nickel mesh), pastes and the multitude of specialised preform shapes demanded by the end users.
