Carbide Tungsten Carbide - What is it?

Carbide is a sintered material and consists of two main components.

On the one hand made of tungsten carbide particles and on the other hand made of cobalt (or more rarely nickel).

The tungsten carbide is the hard phase in the hard metal and forms the hard metal structure with the cobalt as the binder phase.

Hardness, wear resistance and toughness are the main properties of cemented carbide. These properties are influenced by the grain size of the tungsten carbide and the proportion of cobalt. Thus, there are different types of hard metals that can be adapted to their application.

Carbide Tungsten Carbide - The Production

The production of cemented carbide takes place in 6 steps.

After mixing and grinding the hard metal particles with the cobalt, the powder is dried. The powder can then be pressed. Here we differentiate between linear and isostatic pressing. The result is a green compact that can be easily processed mechanically by turning and milling. Finally, the almost finished component is sintered and, after sintering, ground to size or eroded.



Carbide has numerous advantages over other materials, making it an interesting and very important material for many applications.

hardness and wear resistance

The most well-known property of hard metal is its hardness. If you need a material with high wear resistance for an application, you often cannot avoid using carbide. The hardness of hard metals can be adjusted using the grain size of the tungsten carbide and the cobalt binder. Hardness increases with smaller grains and lower binder content. The hardness is usually given by Vickers hardness (HV) and ranges from 690 HV 30 to 2250 HV 30. Thus, the hard metal tungsten carbide is almost as hard as diamond or only diamond is harder than tungsten carbide hard metal.

toughness and breaking strength

The increase and decrease in toughness behaves according to the same rules for cemented carbide as for other materials. If you increase the hardness, you inevitably decrease the toughness. Since all types of hard metal have a high to very high level of hardness, the toughness is significantly lower than that of many other metals. The toughness can be compared to that of hardened steel. Carbide is therefore a brittle material, similar to ceramics there is no plastic deformation before fracture. In order to achieve the highest possible toughness and hardness values, ultra-fine tungsten carbide particles are used for production.

compressive strength

Compressive strength is not to be confused with ultimate strength because, as the name suggests, a different type of stress is applied to the material, namely compression (excluding tension and bending).

Carbide has an extremely high compressive strength when it is uniaxially loaded. With a decreasing grain size of the tungsten carbide and a lower binder content, the compressive strength increases so that a hard metal can achieve a compressive strength of almost 7000 N/mm².

density

Carbide has a higher density than many other metals due to the high density of tungsten carbide of 15.7 g/cm³. The density content varies slightly depending on the amount of binder.

corrosion resistance

Depending on the use of the carbide binder, the surface of carbide is more or less susceptible to corrosion.

If cobalt is used as a binder, this is reduced on the surface by corrosion and the properties of the hard metal are thus negatively influenced. However, if the cobalt binder is replaced with a nickel binder, the corrosion resistance can be significantly increased without affecting the excellent properties of the carbide.
