White fused alumina, also known as white fused aluminum oxide, is a high-performance industrial abrasive and refractory material produced by melting industrial alumina with 99%+ purity at over 2000°C in an electric arc furnace, followed by controlled cooling and crushing. Renowned for its high hardness, excellent self-sharpening, low heat generation, and resistance to acid/alkali corrosion, it is a go-to choice for manufacturing abrasive tools and refractory components across metallurgy, automotive, aerospace, and construction industries. Below, we break down our specialized product lines to help you find the perfect fit for your application.

White Fused Alumina P Series Grits – For Coated Abrasives & Precision Polishing

Our White Fused Alumina P Series Grits are processed on a double-roll production line, resulting in particles with low bulk density, a concentrated particle size distribution, and sharp, multi-angular edges. This unique shape ensures one end of each particle adheres firmly to backing materials (such as paper, cloth, or foam), while the exposed end delivers consistent, aggressive grinding action for precision finishing.

White Fused Alumina Applications:

• Coated abrasives: Sandpaper, abrasive cloth, abrasive belts, fiber polishing wheels, and sponge grinding blocks.

• Precision polishing of wood, metal, and composite surfaces.

White Fused Alumina Specifications:

• Grit sizes: P24, P30, P36, P40, P50, P60, P80, P100, P120, P150, P180, P220 (fully customizable)

• Bulk density range: 1.47–1.88 g/cm³ (adjustable per request)

• Impurity control: SiO₂ ≤0.1%, Fe₂O₃ ≤0.1%, Na₂O ≤0.4%

White Fused Alumina F Series Grits – For High-Toughness Grinding & Precision Manufacturing

Our White Fused Alumina F Series Grits are engineered with advanced smelting technology that optimizes α-Al₂O₃ crystal growth, resulting in higher bulk density and enhanced toughness. This series delivers minimal heat generation, superior thermal stability, and extended tool life, making it ideal for machining high-hardness metals and precision components.

White Fused Alumina Applications:

Grinding tools for high-carbon steel, high-speed steel, and stainless steel (high tensile strength metals); sandblasting, precision grinding, ceramic production, and aerospace/automotive precision manufacturing; abrasive tools requiring extended service life and consistent grinding efficiency.

White Fused Alumina Specifications:

Grit sizes: F12–F220 (customizable)Bulk density range: 1.61–1.85 g/cm³ (minimum values per grit size)Toughness ratings: 30min–63min (optimized for heavy-duty grinding)Impurity control: SiO₂ ≤0.1%, Fe₂O₃ ≤0.1%, Na₂O ≤0.4%.
