Tungsten Carbide - High Precision Machining & Polishing

Tungsten carbide is approximately two times stiffer than steel, with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al 2 O 3 ) or sapphire/ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond, in the form of powder, wheels, and compounds.
