AF K10UF

K10UF is a submicron grade with 6% Co. It is characterized by a very high wear resistance.
As a universal grade it is used for the machining of cast iron, non-alloy and hardened steels, aluminum alloys, non-ferrous metals, composites (CFRP and GFRP), plastics, graphite.

Very suitable for diamond coating.
