Hard materials for wear parts
Hard materials in general and hard metals in particular offer a series of interesting properties for all
applications where maximum wear resistance is required. In practical applications, wear parts are
usually influenced by various interdependent factors: high pressure, high temperature, use of abrasive
or aggressive media, machining of hard materials. These are only some examples of criteria causing
wear, which hard materials or hard metals have to be resistant to. The powder-metallurgical production
of CERATIZIT wear parts enables tailor-made wear resistance of the material.
This is what makes CERATIZIT hard materials and hard metals indispensable when it comes to
decisively increasing the service life of highly stressed components. Ever more powerful machines,
facilities and machining methods create daily new challenges for the CERATIZIT development
engineers. Our development projects are characterised by close cooperation with customers as well as
a joint search for solutions to application problems.
