White Fused Alumina Powder for Glass Polishing White Fused Alumina (WFA / White Corundum) Main component: α-Al₂O₃ ≥ 99.0% (high-purity fused alumina melted above 2000℃ in electric arc furnace) Mohs hardness: 9.0. White fine powder, low iron, low silica, minimal staining risk on glass Also named white aluminum oxide polishing powder / white corundum micro-powder

White fused alumina micropowder is a workhorse in the precision lapping industry. It offers an excellent balance of cutting efficiency, controllable surface finish, and cost-effectiveness. Its high purity, angular morphology, and controlled friability make it the go-to choice for a wide range of applications, from preparing metal specimens for metallography to finishing critical semiconductor and optical components.

white aluminum oxide powder is an indispensable functional material for modern precision manufacturing, advanced materials, and high-temperature industries. Its applications span from traditional finishing processes to cutting-edge fields like semiconductors, aerospace, and advanced ceramics.

White Aluminum Oxide (WA) for Foam Ceramics White Aluminum Oxide (WA), also known as white fused alumina, is a high-purity alumina (Al₂O₃ ≥ 99%) ceramic abrasive with excellent hardness, thermal stability, and chemical inertness. It is a key functional and reinforcing raw material in the production of foam ceramics, widely used to enhance mechanical properties,

White Aluminum Oxide (WA) powder is a high-performance functional filler for industrial coatings, automotive paint, repair paint, topcoat, primer, and high-temperature coatings.

Industrial grade WFA (Al₂O₃ ≥99.0%, Na₂O 0.20%–0.40%) is the most common economical grade, widely used in abrasives, refractories, sandblasting and ceramic industry
