White Fused Alumina Abrasive
White fused alumina is a high-purity aluminum oxide abrasive material produced by fusing alumina in an electric arc furnace. The sharp, angular grains of this material provide excellent cutting performance in precision grinding, polishing, and lapping applications, and it is also a component in refractory linings.
Technical Specifications
Product Overview
High-Purity Industrial Abrasive
White Fused Alumina is a premium-grade abrasive material produced by melting high-quality alumina in an electric arc furnace at temperatures exceeding 2000°C. Composed primarily of alpha-Al2O3, this material is celebrated for its exceptional hardness and chemical stability. It serves as an essential component in refractory applications, furnace burdens, and high-performance abrasive tools.
