- Product Introduction
Products Description
Brown Aluminum Oxide (Brown Corundum) is a high-performance abrasive material produced by smelting high-quality bauxite, anthracite, and iron filings in an electric arc furnace at extreme temperatures. With an Al₂O₃ content of 95%-97%, it delivers exceptional durability, heat resistance, and grinding efficiency. Minor traces of Fe, Si, and Ti enhance its structural integrity, making it a top choice for demanding industrial processes.
Key Properties & Advantages
Superior Hardness – Ideal for grinding, cutting, and surface preparation.
High-Temperature Resistance – Withstands extreme heat, perfect for refractory applications.
Excellent Corrosion Resistance – Long-lasting performance in harsh environments.
Versatile Applications – Used in steel, cement, glass, and chemical industries as a refractory material and abrasive.

Why choose us
At the core of our premium brown fused aluminum oxide (BFAO) abrasives lies a commitment to uncompromising quality, advanced refining processes, and strict production control. Here's what sets us apart:
1. Premium Raw Material Selection
We source only high-grade abrasive bauxite with Al₂O₃ content exceeding 85%, ensuring superior hardness and durability right from the start. Our skilled workers meticulously handpick the finest ore to guarantee optimal purity and performance.
2. Double Refining for Enhanced Performance
Unlike standard production methods, we subject our brown corundum to an additional 3 hours of secondary refining beyond industry norms. This extended smelting process eliminates impurities, enhances grain toughness, and delivers a sharper, more consistent abrasive grain structure.
3. Precision Grading & Screening
Every batch of crushed brown corundum undergoes strict manual grading to ensure uniform particle size distribution. This attention to detail guarantees maximum cutting efficiency, reduced waste, and longer-lasting abrasive performance.
4. Advanced Purification Technology
Our high-power 5-channel magnetic separators aggressively remove iron and silicon impurities, resulting in ultra-clean abrasives with minimal contamination. This advanced purification process enhances grinding efficiency and minimizes defects in finished products.
5. Rigorous Quality Assurance
From raw material inspection to final packaging, our dedicated QC team enforces stringent testing at every stage. With a skilled technical team and disciplined production protocols, we ensure every shipment meets the highest industry standards.
