What is the coating material of ceramic coated white fused alumina?

Ceramic-coated white fused alumina, commonly known as iridium-coated WFA. It is a high-grade abrasive grain made by applying a special coating process to white fused aluminum oxide and then calcining it. The ceramic coating significantly improves the toughness, hydrophilicity, and self-sharpening properties of WFA. Thus, it results in even better performance for cutting blades and other grinding wheels. The color of the coating varies depending on the coating material.

The advantages of White Aluminum Oxide Polishing Powder?

White Aluminum Oxide powder offers significant advantages. It’s not only gains features of  high purity and impurity-free performance, high hardness, strong cutting performance, excellent self-sharpening properties, high efficiency. But also, WFA powder has stable chemical properties with uniform particle size, high surface quality, and a wide range of applications. White Aluminum Oxide polishing powder is also called White corundum powder or white fused alumina Powder. It is an electro fused corundum powder.

99.8% WFA F100 for vitrified abrasive grinding wheel

99.8% WFA F100 White Fused Alumina grain is mostly adopted maetrial in vitrified bond grinding tools.  High purity WFA F100 grain obtain excellent self-sharpening properties and grinding force, can significantly improve grinding efficiency, durability, and machining precision. Low-sodium 99.8% white corundum grain offers superior performance compared to ordinary white corundum abrasives.

White Fused Alumina F16 Applications

White fused alumina F16 (White corundum 16 mesh) belongs to coarse-grained WFA abrasives.  In the F series, the smaller the number, the coarser the grain size. F16 has a particle size of approximately 1.0-1.40mm. Its key characteristics include high hardness (Mohs hardness 9, second only to diamond), moderate toughness, high grinding efficiency, and good corrosion resistance and insulation properties. Its applications mainly focus on rough grinding, efficient material removal, and surface pretreatment. And It is widely used in the initial processing stages of various fields such as stainless steel, alloys,etc.

White corundum powder 400# 500# for denture sandblasting

White corundum micropowder 400#  500# are made from industrial alumina powder. It gets from fusing process in an arc at temperatures exceeding 2000°C, and then cooled. They are widely used in denture sandblasting. The particle size range of 400-mesh white corundum is 20-60 microns, and the particle size range of 500-mesh white corundum is 15-55 microns. They offer the following advantages as denture sandblasting media

EU imposed provisional anti-dumping duties on fused alumina from China

On July 18, 2025, the European Commission issued a preliminary affirmative anti-dumping determination on fused alumina raw materials (artificial corundum) originating in China and decided to impose provisional anti-dumping duties. The provisional anti-dumping duties range from 111.29% to 136.3%.

WFA F80 for Agricultural machinery blade blasting

WFA F80 is a type of abrasive material. The main chemical of WFA F80 is artificial corundum with excellent grinding capability.  It offers several advantages when used for blasting agricultural machinery blades:

WFA F060 F080 powder for Two-component Epoxy Floor Varnish

WFA F060 F080 powder are good anti-skip additives of two-component epoxy floor varnish. The functions of WFA are increasing wear resistance and anti-skip properties, improving the corrosion resistance and weather resistance of floor paint, etc.  WFA is another name of white fused aluminum oxide or white corundum.

WFA F036 for railway locomotive sanding

WFA F036 is an artificial white fused alumina abrasive sand. The particle range of WFA F036 is 0.425-0.6mm, it is suitable for high-speed rail locomotive sanding and braking.
