The process for making tungsten carbide is simple. Equal parts powdered tungsten and carbon are mixed together along with a metallic binder. The most common binders currently in use are cobalt and nickel. The mixture is compacted into a shape, and it's then heated to above the melting point of the binder. The tungsten carbide, which is powdered, is then surrounded by the molten binder. As the slurry dries, the binder holds the tungsten carbide in a matrix that's extremely hard and durable. tungsten carbide that uses a bonding agent is a composite metal, but it's rarely an issue.
