White Fused Alumina Abrasive Sand 1-3mm
White fused alumina section sand is used as a refractory media. Its sharp, angular grains provide aggressive cutting action and excellent surface finish.
Technical Specifications
Product Overview
High-Purity White Fused Alumina
White Fused Alumina is produced by melting high-quality alumina in an electric arc furnace at temperatures exceeding 2000°C. This industrial-grade abrasive features a high-purity crystalline structure of alpha-Al2O3. Renowned for its excellent thermal shock resistance and chemical stability, it is an essential material for refractory applications, castables, and precision surface preparation.
