1. What is White Fused Alumina (WFA)?
White Fused Alumina (WFA) is a high-purity abrasive material made by melting high-quality bauxite in an electric arc furnace. WFA is widely used in abrasive tools, refractory products, and sandblasting media due to its exceptional hardness and purity.
2. How is White Fused Alumina produced?
White Fused Alumina is made by melting high-grade bauxite at temperatures above 2,000°C (3,632°F) in an electric arc furnace. After melting, the material is cooled, crushed, and sized into various grades to meet different application needs.
3. What is the difference between White Fused Alumina and Brown Fused Alumina?
White Fused Alumina: Known for higher purity, greater hardness, and precise granulation, making it perfect for fine grinding, polishing, and precision applications.
Brown Fused Alumina: More durable, tougher, and ideal for heavy-duty grinding and sandblasting applications.
4. What are the main uses of White Fused Alumina?
White Fused Alumina is used for:
Abrasive tools: Making grinding wheels, sandpaper, and polishing compounds.
Refractory materials: Producing heat-resistant bricks and casting materials.
Sandblasting: Ideal for surface cleaning, rust removal, and surface preparation in a variety of industries.
5. Is White Fused Alumina environmentally friendly?
Yes, White Fused Alumina is a non-toxic, recyclable material. It produces low dust emissions during use and is considered a safe, eco-friendly abrasive for workers and the environment.
6. What benefits does White Fused Alumina offer in abrasive tools?
