CTD manufactures all types of cemented carbide wear parts to size. The possibilities are almost limitless.
Although cemented carbide already exists for more than a 100 years, the material is still not well enoughy known. The exceptional properties of cemented carbide make it particularly suitable for many wear applications.
Cemented carbide also called tungsten carbide or just carbide, consists of exceptionally hard tungsten carbide particles in a ductile metallic binder mostly Cobalt (Co) or Nickel (Ni). This hybrid structure gives cemented carbide its unique feature of combining extremely high hardness with very high compressive strength and good toughness. Other properties of cemented carbide are a high hot hardness and good corrosion resistance.
By varying the carbide grain size and the metal binder composition and content, cemented carbide can be fine tuned in order to obtain optimized properties like :
Cemented carbide is a material that is produced by powder metallurgy starting from carbide particles and metal powder. The production process and the purity of the powders are decisive for the final quality of the finished part. Therefore it is very important to make to correct choice of cemented carbide for each application.
CTD will use its year-long experience in carbide properties and applications to advice you in the right choice for your application.
1. Abrasive wear
Because of the very high hardness and corrosion resistance, carbide has an exceptional resistance against dry and wet abrasion resistance.
Some applications are:
The compressive strength and toughness makes cemented carbide the preferred material to cut all types of material.
3. Bending, rolling, extrusion
The high hardness of the carbide grains increases the galling resistance.
4. Shredding, grinding and mixing
Cemented carbide is exceptionally suitable for shredding, grinding and mixing of different materials.
