Brown Fused Alumina
Brown fused Alumina known as “artificial corundum” or “alumina
grit”. Brown fused alumina is produced from bauxite,
charcoal, iron chip by being fused under high temperature in an
electric arc furnace. It is characterized by high toughness and has
a micro hardness of ********0kg/mm2. The abrasive tools made by
brown fused alumina are suitable for grinding carbon steel, normal
alloy steel, malleable cast iron and hard bronze, etc. Brown fused
alumina can also be used for making fine quality refractory
etc.
