Alumina-based ceramics are without a doubt the largest selection of progressive ceramics machined by PFC. Aluminium Oxide (or Alumina), Al2O3, is a leading engineering material. It provides a blend of excellent electrical and mechanical properties, providing the means for a broad spectrum of functions.
Wear Resistance - Industriekeramik Hochrhein GH
Wear Resistance Good wear protection makes an important contribution to increasing the service life of machines, to saving costs and preventing production losses. On the material side, the hardness and the abrasion properties are particularly important compared to rubbing, impacting or scratching stress [Foc14]. The fact that locally extremely high pressures and temperatures occur on […]

Tungsten Carbide is around twice as stiff as steel with a Young''s modulus of over 500 GPa and a low electrical resistivity of around 0.2 mW.m. In terms of hardness it is comparable to Sapphire or Ruby, ranking 9 on Mohs scale and requires cubic boron nitride or diamond tools and abrasives to be ground and polished into finished components.
