What Is Fused Alumina?
Fused alumina is a high-hardness synthetic mineral produced by melting alumina-bearing raw materials in an electric arc furnace. Because of its excellent hardness, thermal stability, wear resistance and chemical stability, fused alumina is widely used in bonded abrasives, 涂附磨具, blasting media, 耐火材料, 磨削, lapping and polishing applications.
- High Hardness: Strong cutting performance for grinding and blasting.
- Wear Resistant: Durable under high-friction working conditions.
- High Purity: Low impurity content for stable product quality.
- 化学稳定性: Stable performance in demanding industrial applications.
Brown vs White vs Black Fused Alumina
Brown Fused Alumina is better suited for applications emphasizing hardness, 韧性, and wear resistance; White Fused Alumina is more appropriate for applications prioritizing purity, low iron content, and precision; Black Fused Alumina is best positioned as a more economical material for sandblasting, 抛光, and resin-bonded abrasives.
