Understanding the Matrix in Tungsten Carbide Cutting Tools

Cobalt is the matrix in tungsten carbide cutting tools. The cemented carbides, which are commonly used as cutting tool materials, consist of hard substances like tungsten carbide along with a matrix material. In the case of tungsten carbide cutting tools, cobalt is used as the matrix.

Tungsten carbide-cobalt cutting tools are metal matrix composites, where the tungsten carbide serves as the aggregate material, providing hardness and wear resistance, while cobalt acts as the binder, holding the tungsten carbide particles together and providing toughness to the tool.

The use of cobalt as the matrix material in tungsten carbide cutting tools ensures that the tool maintains its strength, hardness, and durability during cutting operations. The combination of tungsten carbide as the aggregate and cobalt as the matrix results in a tool that can withstand high temperatures, resist wear, and maintain sharp cutting edges for longer periods of time.
