Tungsten Carbide

Tungsten carbide is one of the hardest and most wear-resistant materials available. It is often used for die components in high volume manufacturing situations. It also used for machine parts that come in contact with very abrasive materials.

Tungsten carbide is a combination of tungsten carbide powder and a binder metal, such as cobalt or nickel, which holds the tungsten carbide powder together. By adjusting the percentage of binder metal, tungsten carbide components can be made very wear resistant but brittle or very durable but not as wear resistant.

Very smooth, polished finishes can be produced on tungsten carbide components which improves wear resistance of the component and aids significantly in metal forming applications.


Thin Film Surface Treatment Coatings

Thin film surface treatment coatings are very popular for the tungsten carbide tools in these days. The coatings offer significant increases in tool life at a low cost. Tungsten carbide is the one of the best substrates for these coatings. While Grand does not apply these coatings in house, Grand do work with all the major coating companies.

Grand has the knowledge and experience in how to best prepare parts for coating, and we also know how to polish the coating afterwards to maximise performance.
