TUNGSTEN TITANIUM CARBIDE - Improved high temperature performance for carbides

Tungsten titanium carbide (W,Ti)C is one of the most important composite carbides in the production of high performance hard metal for metal cutting, e.g. in automobile and machine tool manufacture.

With the addition of titanium carbide, tantalum carbide or composite carbides such as tungsten titanium carbide (W,Ti)C, the high temperature properties of hard metals, such as hot hardness or resistance to oxidation and diffusion, improve significantly in comparison with iron-based alloys.

Tungsten Titanium Carbide

Here, as a composite carbide rather than a single carbide, tungsten titanium carbide features advantages such as greater hardness, better high temperature strength and better wettability by cobalt.

Grades with various W/Ti ratios and grain sizes

H.C. Starck offers two grades of high quality tungsten titanium carbide powder with various tungsten/titanium ratios: in the standard grade (W,Ti)C S the ratio is 50/50. The (W,Ti)C HV grade with even fewer impurities is available with a 50/50 ratio and a 70/30 ratio. Both grades are available with grain sizes of 1 µm and 3 µm. We provide technical support in the selection of the suitable powder and for questions regarding process optimization.

To ensure a sustainable supply of raw materials, we also recycle tungsten from secondary raw materials. In this way, hard metal scrap that contains tungsten titanium carbide is used to produce new, high quality tungsten carbide and tungsten titanium carbide powder that can be used again in hard metal production. Tungsten recycling is offered either by purchasing used materials or by reprocessing a certain tungsten product.
