Tungsten carbide and its shapes

With DURMAT® achieve improved, higher-performance wear alloys

The high demands made today on the wear resistance of alloys based on Tungsten carbide and Cobalt are leading to ever finer microstructures with optimized compositions. This results in improved, higher-performance wear alloys.
