325 Mesh & 200 Mesh White Fused Alumina Powder 99.5% Al2O3 for Fireproof Materials and Industrial Polishing

White fused alumina (WFA) is a high-purity synthetic abrasive material manufactured by fusing alumina in an electric arc furnace at elevated temperatures. With a primary crystal structure of corundum (Al₂O₃), this material delivers exceptional hardness, strength, and chemical purity for demanding industrial applications.

• High Al₂O₃ purity (≥99%) ensures superior hardness and grinding efficiency
• Exceptional wear resistance maintains strength even at high temperatures
• Water suspension treatment provides excellent flowability and dispersion
• Low oil absorption, particularly suitable for water-based paints
• Neutral pH value (7-8) ensures compatibility with various materials
• High whiteness doesn't affect the color of paints or coatings
• Resistant to most corrosive alkalis and acids, insoluble in water
• High temperature resistance up to 1900°C
• Consistent particle size distribution prevents substrate scratching

• Grinding and Polishing: Manufacturing of abrasive wheels, belts, and discs for precision grinding of metals, ceramics, and composites
• Surface Preparation: Removal of scale, rust, paint, and contaminants from metal substrates
• Refractories: Production of firebricks, refractory castables for steel, cement, and glass industries
• Precision Casting: Investment casting molds and cores for high-dimensional accuracy
• Abrasive Blasting: Surface cleaning, etching, and preparation in metal fabrication, automotive, and aerospace
• Superabrasives: Precision grinding of hard materials like high-speed steels and ceramics
• Ceramics and Tiles: Additive for improved strength, hardness, and thermal shock resistance
