TUNGSTEN CARBIDE
53
In all shapes, sizes and grades
We would be pleased to advise you on the many options for
using tungsten carbide and, on request, can also produce
unusual shapes for you.
Just tell us what problem you have with abrasive wear.
We'll find you an economic solution – even for areas
of use where until now steel has provided the abrasive
wear protection.
Our guarantee: We always match the tungsten carbide
grade to the intended use. That ensures the necessary
toughness while simultaneously providing good resistance
against wear.
