Cemented Carbide from CERATIZIT for High Wear Demands
What is cemented carbide?
Cemented carbide is a composite consisting of a hard material and a very tough binder metal. The material is extremely hard, characterised by high wear resistance and high hot hardness. It is used wherever tools or components are exposed to high wear, as is the case when cutting hard materials. Carbide improves the quality of tools and components, gives them a longer service life and ensures that processes are safe and reliable.
CERATIZIT manages the entire production process chain of cemented carbide and cemented carbide components, from powder preparation to forming, sintering, finishing and surface treatment. The blanks are subjected to grinding, polishing and EDM machining and are then given an innovative wear-resistant coating, when necessary. This ensures that our carbide products have the properties required for industrial applications.
Cemented carbide and cemented carbide components are made from extremely hard tungsten carbide and ductile cobalt. The two substances are mixed in the form of powder.
To make a finished carbide part from a powder mix, you first need to press it into a mould. The resulting green compact or carbide blank can then be machined. But only after the sintering process does it become a homogeneous and dense cemented carbide.
The machining of the cemented carbide has a decisive impact on the properties and characteristics of the tools and preforms. Qualitative accuracy of the individual machining stages can make a real difference to tool life.
Most common joining techniques can be used for cemented carbide. They can be divided into three categories: material joints, power joints and shape joints.
What are the application fields of cemented carbide tools?
Cemented carbides are used today in numerous industries and production processes, which would be unthinkable without them. Complex products and modern materials make ever higher demands, in terms of tooling and material standards and call for machining accuracy, in the following fields for example:
