Aluminum Oxide

Silicon
Carbide

Extremely hard and sharp, but fractures more easily than aluminum oxide.
Performs well on Cast Iron, Nonferrous Metals (Aluminum) and Non-Metalic materials including Concrete, brick, marble and glass.

Zirconia Alumina

Very tough, sharp, and dense.
Lends itself to higher temperatures and heavier pressures present in high-stock removal applications.

Ceramic

Sharp microsrystalline grain-cuts aggressively under light to moderate pressure.
Its quick cutting capability makes it suitable for grinding stainless steel, titanium and high-nickel alloys.
