Brown corundum grit/ powder for glass grinding

Description

Brown fused alumina is made by high quality bauxite as main material, fusing and purifying in a pouring electrical at a temperature of over 2200 °, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc. With suitable hardness, it can be used for grinding material to deal with watch surface or glass etc.

Advantages of BFA

• High hardness
• Crystallinity
• Good fluidity
• Little adhesion
• No detenate, crack, and pulverization during use

Usage of BFA
