FUSION W is a Flux cored hardsurfacing wire containing 50-60% cast tungsten carbide suspended in a nickel alloy matrix. It has a combination of toughness and wear resistance, due to the heterogeneous weld metal composed of tungsten carbides distributed in a hard and very tough matrix. Unlike many others, this welding wire has exceptional wetting characteristics. It performs best in applications that endure extreme abrasion combined with or without corrosion.
Common applications include:
Brick/Clay Mill Augers
Earth Drilling Tools
Earth Moving Equipment
Fan Components
Mining Equipment
Rubber Mixers
