Product Introduction of White Fused Alumina #240
White Fused Alumina #240 is a high-purity abrasive grain designed for grinding, polishing, lapping, and surface preparation applications. Produced from high-quality alumina through an electric arc fusion process and subsequent processing, it offers excellent hardness, sharp cutting action, good chemical stability, and consistent abrasive performance.
With its controlled particle size distribution, White Fused Alumina #240 provides an effective balance between cutting efficiency and surface finishing performance. The hard and sharp alumina particles can remove material efficiently while helping produce a clean and uniform surface during grinding, polishing, and finishing processes.
White Fused Alumina #240 is widely used for processing metals, ceramics, and other industrial materials. Its high purity, white color, and stable physical properties make it suitable for applications where consistent abrasive performance and a clean working surface are important. Particle size distribution, packaging, and other specifications can be customized according to customer requirements.
