• Regular Brown:
  • Tough form of aluminium oxide.
  • 96% pure. Hardness around 18.5 GPa.
  • Toughness imparted by metal oxides.
  • For grinding high tensile strength materials, as well as rough grinding, deburring, snagging, cutting and fettling of low-alloy, ferrous materials.
• White:
  • High friability.
  • 99% pure. Hardness around 19.5 GPa.
  • Friability imparts high speed and cool cutting grinding characteristics, making it suitable for grinding hardened and high alloy steels up to 62 Rc.
• Pink:
  • Slightly less friable than white but a little tougher
  • pink in colour due to the addition of metal oxides.
  • 99% pure. Hardness around 19.0 GPa Knoop.
  • Can be used in similar applications to WA and in particular highly alloyed tool steels

• Black:
  • Harder than aluminium oxide at 24 GPa but more brittle.
  • Used when grinding low tensile materials like cast iron, non-ferrous and non-metallic.
• Green:
  • preferred by carbide tool grinders.

• Zirconia complex.
• 16 GPa.
• A tough abrasive which has good thermal stability at grinding temperatures.
• Tends to be used in steel mills and foundries.

• A unique microstructure imparts good durability and high stock-removal rates.
• The combination of hardness and toughness endows this type of grain with the ability to cut both ferrous and non-ferrous materials.
