Brown Fused Alumina
The main material of brown fused alumina is bauxite, which is electrically fused in high temperature.
It is brown and featured high hardness and toughness.
The abrasive tools made of it are suitable for the grinding of carbon steel, malleable cast iron, hard bronze, etc.
In addition. they are used as refractory materials, chemical additive, precision founding and anti-sliding materials.
