Diamonds are made of pure carbon and are the hardest known abrasive. Diamonds are extremely effective for working:

  • Carbide metals, also persintered
  • Carbide metal
  • Tools and construction units
  • Hardfacing
  • Hard-faced wear alloys
  • Ferro-TiC® and Ferro-Titanit®
  • Steatite, earthenware
  • Oxide ceramic materials
  • Ferrite, ceramic magnetic materials
  • Ceramic grinding elements
  • Refractory products
  • Natural and artificial stone
  • Gems and semi-precious stones
  • Glass, porcelain, quartz
  • Silicon, germanium
  • Graphite, carbon
  • Plastics, fibre-glass-reinforced plastics


Cubid boron nitride is far superior to classic abrasives such as aluminium oxide and silicon carbeide in term of hardness and does not react chemically with steel and higher temperatures. Which means that CBN is the ideals abrasive for

  • High-speed steel tools
  • High-Alloy tool steels
  • Chromium steels (12% CR)
  • and carburizing steel
