Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other raw materials.
It is characterized by its high cleanliness,super grinding capacity and high compression strength.
Abrasives made by is no rusty spot, greatly improved grinding efficiency,applicable to make high-grade resin bonded abrasives.
