Widia carbide inserts

Widia hardmetal plates are components made of sintered hardmetal. They consist predominantly of tungsten carbide that is bonded with a metallic binder, usually cobalt. This combination of materials gives the plates very high hardness and exceptional wear resistance.

The term “Widia” is a protected brand name and is derived from “like diamond.” The trademark rights have passed from Krupp to Kennmetal Inc. In technical parlance, “Widia” is often used today as a synonym for particularly hard hardmetal materials, even though strictly speaking it is a brand-specific designation. Widia hardmetal plates are used wherever components are heavily stressed by abrasive media. Typical applications are mixing tools, spirals, cutting edges, impact surfaces, or conveying elements in bulk material and process engineering. They protect base bodies made of steel from premature wear.

In mixers, reactors, and processing plants, for example, they significantly extend the service life of tools. This reduces maintenance intervals and increases plant availability. They are of particular importance with abrasive powders, minerals, or metal powders.

Depending on the application, the plates are welded on, soldered, or mechanically fastened. Their geometry and positioning are adapted to the product, the stresses, and the process conditions.
