» EVERYTHING FROM A SINGLE SOURCE

Cemented tungsten carbide is a sintered material mainly consisting of tungsten carbide

and a binding agent. The main binder is usually cobalt. If the focus is on creating corrosion

resistance, nickel or nickel/chromium is the perfect binding agent.

It’s the mix that matters: The binder content and the grain size of the carbides determine the

specific tungsten carbide features. A high content advances toughness. A lower binder content

increases wear-resistance. The choice of grain size in turn affects hardness. The finer the

grain, the harder the material. The coarser the grain, the higher the fracture toughness.

The best composition depends on the technical requirement and the respective application.

Due to long-standing experience and the broad expertise of our technicians and engineers,

we are able to realize the suitable component in the precisely accurate material composition.

At maximum precision. For you!

The tungsten carbide experts at DURIT are able to manufacture blanks in complex

geometries and components of almost any size. In this respect, the material composition

and the degree of hardness are determined by the application purpose. The production in

our advanced HIP sintering systems achieves a homogeneous quality level with best

physical features. Our customers benefit from a unique production and dimension range:

from the production of small parts starting at a hole diameter

of 0.5 mm to large components with an outside diameter of

up to 500 mm. As a provider experienced in developing and

processing special grades of tungsten carbide, we are able to

adapt them to your special requirements – in a well-aimed way.

Sustainability becomes an economic factor

Crushing tough products or materials puts extreme

demands on all applied tools and components. In this

field, tungsten carbide also features a much higher

break resistance than ceramics and a far higher wear-

and pressure-resistance than steel or other materials.

That is why tungsten carbide becomes more and more important in the growing recycling industry as well as in the

field of industrial processing of abrasive media. Particularly suitable for processes like milling or crushing, tungsten

carbide decisively contributes to a higher productivity – in more and more companies. On that score, the experts at
