Purity constraints: Our purity processes allow us to achieve extremely low impurity levels, to below 5 ppm. The ETV-ICP method is used to detect and monitor impurities to levels below 5 ppb. Cleanliness constraints: Vitreous Carbon Impregnation (VCI) was developed to reduce particle emissions and the vacuum outgassing of materials, particularly for semi-conductor appliions.

From cast iron machining to steel machining to drilling of non-ferrous metals, Inconell, plastics, GFK, CFK (composite materials), graphite and much more. With new cutting materials such as AlOx (aluminium oxide) or SiX+DIA (silicon ceramics+diamond coating) we are breaking new ground in the processing of CFRP (carbon fibre composites), graphite and high silicon aluminium.
This coating is used to infiltrate and seal porous graphite, carbon fiber composites, and similar porous substrates used in harsh environments. GraphiSeal has even been used to seal porous ceramics. For additional enhanced properties GraphiSeal can be coined with particulate fillers such as alumina, silicon, SiC, and other fillers to modify both internal and coated surface properties.

Carbon and graphite materials are resistant to chemical agents - no other traditional material has such a wide range of properties and appliions. The most important feature of carbon and graphite in this appliion is their resistance to almost all chemical compounds in a wide temperature range, except for strong oxidizing substances.

Tungsten carbide - Wikipedia
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery , cutting tools , abrasives , armor-piercing shells and jewellery .
