Brown fused alumina, also known as brown aluminum oxide or brown corundum, is an industrial abrasive made by fusing bauxite in an electric arc furnace at temperatures above 2000°C. This process creates a dense crystalline structure that provides excellent cutting ability and impact resistance. Compared with ordinary abrasives, brown fused alumina offers a balanced combination of sharpness and durability, making it suitable for both bonded abrasives and coated abrasive applications.
Specifications
Brown fused alumina Key Features
High toughness & impact resistance
Our brown fused alumina abrasive resists grain fracture during grinding, which helps maintain consistent cutting performance in resin bonded grinding wheels and cutting discs.
Stable hardness for controlled material removal
With a Mohs hardness of around 9, brown aluminum oxide offers strong cutting ability without excessive wear, ideal for steel grinding and metal fabrication.
Uniform grain size distribution
Precision sieving ensures consistent abrasive grain size, improving wheel balance and surface finish quality in industrial grinding wheel production.
Excellent thermal stability
High melting-point fusion enhances heat resistance, reducing burning and discoloration during high-speed grinding operations.

FAQ
Q: What is the difference between brown fused alumina and white fused alumina?
A: Brown fused alumina contains slightly less Al₂O₃ but offers higher toughness, making it more suitable for heavy-duty grinding and metal removal.
Q: Is your brown aluminum oxide suitable for resin bonded grinding wheels?
A: Yes. Our abrasive grains are optimized for resin bonded grinding wheels and cutting discs, providing stable cutting speed and long service life.
Q: What grit sizes do you supply?
A: We offer FEPA standard grit sizes from F12 to F220, with custom grading available upon request.
Q: Can you provide consistent quality for large-volume orders?
A: Absolutely. As an experienced brown fused alumina manufacturer, we control raw materials, fusion temperature, and grading processes to ensure batch-to-batch consistency.
Q: Do you support OEM or private label customers?
A: Yes. We support customized packaging, labeling, and technical specifications for distributors and abrasive manufacturers.
