Refractory brown fused alumina/BFA

Refractory brown fused alumina/BFA Specification: High hardness High toughness Resistance of high-temperature Anti-oxidation Corrosion resistance Introduction: Brown fused alumina is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°c, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid cleaning, etc. Application: Brown fused alumina is widely used as a raw material in refractory, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding nad hundreds of other applications. Brown fused alumina grains and powders are available in standard grit and powder sizes and can be made to individual specifications.
