Medium to coarse WC grain size

Medium to coarse WC grain sizes provide the cemented carbides with a superior combination of high hot hardness and toughness. These are used in combination with CVD or PVD coatings in grades for all areas.​

 

Fine or submicron WC grain size

Fine or submicron WC grain sizes are used for sharp cutting edges with a PVD coating to further improve the strength of the sharp edge. They also benefit from a superior resistance to thermal and mechanical cyclic loads. Typical applications are turning super alloys, solid carbide drills, solid carbide end mills, parting off and grooving inserts, milling and grades for finishing.

 

Cemented carbide with gradient

The beneficial dual property of gradients is successfully applied in combination with CVD coatings in many first choice grades for turning, and parting and grooving in steels and stainless steels.
