Brown Fused Alumina for Wear-Resistant Components
Engineered hardness and thermal resistance for reliable wear protection in industrial applications.
Why Use BFA in Wear Components?
Brown fused alumina (BFA) is a preferred material in producing ceramic and composite components subject to heavy abrasion, friction, or particle erosion. Its high hardness and thermal resistance make it suitable for use in dynamic environments where traditional metals or polymers fail.
- Mohs 9.0 hardness for exceptional abrasion resistance
- Thermal stability above 1800°C in hot wear zones
- Chemically inert under corrosive or high-pH conditions
Common Applications
- Ceramic-lined wear plates and deflector tiles
- Blast nozzles, chute liners, and cyclone separators
- Sealing rings and bearing surfaces
- Valve seats and pump internals in slurry systems
Used in mining, cement, steelmaking, and petrochemical industries.
Recommended Grain Sizes
- Shaped ceramics & tiles: 0–1 mm, 1–3 mm aggregates
- Spray coatings or sintered layers: F46–F120
- Structural microgrit fillers: F150–F320
Available in angular, semi-angular, or spheroidized grain forms to suit shaping processes.
