White Aluminum Oxide Abrasive
White aluminum oxide is a high-purity abrasive material produced by fusing alumina in an electric arc furnace. It is used in grinding wheels, polishing powders, and lapping compounds.
Technical Specifications
Product Overview
High-Purity White Aluminum Oxide
White Aluminum Oxide is a high-purity abrasive produced by melting high-quality alumina in an electric arc furnace at temperatures exceeding 2000 degrees. Featuring a primary crystal phase of alpha-Al2O3, this material is celebrated for its exceptional hardness and sharp cutting edges. It is a chemically inert, high-performance solution ideal for precision grinding, refractory applications, and surface finishing across ferrous and non-ferrous metals.
