White Fused Alumina Powder

White Fused Alumina Powder is produced by the grinding & classification of selected Macro grain feedstock in advanced milling and classifying facility. This ensures an iron-free product of narrow particle size distribution and high whiteness. The sizes are controlled and tested using an x-ray sedimentation particle size analyzer and particle counter. The White Fused Alumina Micro grits generally conform to the FEPA (Federation of European Producers of Abrasives) specifications. JIS, GB, and other customer-specific sizes can be supplied as required.

White Fused Alumina Micro Powder​ is a finer grade White Fused Alumina Powder with main content Aluminium Oxide(Al2O3) made sieved by water pressure. It’s a single crystal, self-sharpening, abrasion-resistant abrasives for precision grinding, polishing, cutting, etc. White Fused Alumina finer grades are further graded into China GB, FEPA, JIS, or ANSI standards for precision abrasives, cutting, blasting, or polishing. It’s also used for precision abrasive tools for special equipment.

White Fused Alumina Fine Powder‘s property is more concentrated in particle size distribution than an ordinary fine powder, making refractory and foundry the application effect better.
