White corundum powder is a good additive for FRP products. It can improve the strength of FRP.

White fused alumina (briefly WFA) is a common refractory material. It works as refractory aggregates and refractory castables a lot. Let’s explore the relationship between WFA aggregate and WFA castable.

White aluminum oxide powder 20 micron is equivalent to WFA JIS800 mesh. White aluminum oxide 20 micron is sutiable for stainless steel polishing, industrial ceramic raw materials and other industries.  It is also a good finishing media for blasting. 

Sandblasting is a process in which abrasive particles are driven by the strong pressure of air to grind the surface of stainless steel. White fused alumina grit is an aggressive blasting media for stainless steel surfaces. It is of high hardness and grinding power. In the blasting process, each particle of white fused alumina grain is like an irregular cutter. When this granular “cutter” cuts stainless steel, the scratch marks different surface roughness.

White fused alumina refractory material is an excellent high thermal raw material. It has high refractory temperature, strong thermal shock resistance, and high density. It can be used in various shaped and unshaped refractory materials in industries such as steelmaking, steel ladle, kiln furniture, refractory aggregate, and castables.

The white fused aluminum oxide powder is an excellent polishing powder. It is not only for metal, iron, or stainless steel. But also works well for plastic, stone, wood, resins, etc.

The hydrophilicity of white aluminum oxide is its ability to attract water molecules. The hydrophilicity of the white aluminum oxide is very important for resin-bonded abrasive wheels.

The hardness of white fused aluminum oxide is 9.0 on the Mohs scale.  And Knoop hardness of white fused aluminum oxide is 20500N/MM2.  It is harder than most metal, stainless steel, and alloy parts. Therefore, it can grind most metals, iron, stainless steel, and other materials.
