Tungsten Carbide
MGGS offers good quality Tungsten Carbide products, it comes from a family of metal matrix composites commonly referred to as cemented carbide. Tungsten carbide, being comprised of the elements tungsten (W) and carbon (C), is further enhanced through the addition of a metallic binder such as cobalt or nickel. Production of tungsten carbide is achieved by mixing the ultra fine powders, compacting to form a shape and then sintering at a temperature above the melting point of the metallic binder.
The molten binder surrounds the carbide particles and bonds the matrix together producing an extremely hard and tough composite material. Due to its high hardness and excellent impact resistance, tungsten carbide is commonly used in applications ranging from cutting tools to mining operations. The toughness and hardness properties can be tailored to specific application requirements by adjusting the binder content.
