Product Introduction of White Fused Alumina #20
White Fused Alumina #20 is a high-purity abrasive grain designed for abrasive blasting, grinding, surface preparation, and other industrial abrasive applications. Produced from high-quality alumina through an electric arc fusion process and subsequent processing, it offers excellent hardness, sharp cutting performance, strong wear resistance, and good chemical stability.
With its coarse #20 abrasive grade, White Fused Alumina #20 provides efficient material removal and effective surface preparation. Its hard and sharp abrasive particles are suitable for removing rust, coatings, scale, and surface contaminants while providing consistent and controlled abrasive action.
White Fused Alumina #20 is widely used for metal surface treatment, abrasive blasting, grinding, refractory processing, and general industrial surface preparation. Its white color, high purity, and low impurity content make it suitable for applications where a clean abrasive medium and low surface contamination are important. Particle size distribution, packaging, and other specifications can be customized according to customer requirements.
