White fused alumina and brown fused alumina are two commonly used abrasives. Many people do not know the direct difference between the two except for the color. Now I will take you to understand.
Although both abrasives contain alumina, the alumina content of white fused alumina is over 99%, and the alumina content of brown fused alumina is over 95%.
White fused alumina is produced from alumina powder, while brown fused alumina contains anthracite and iron filings, plus calcined bauxite. White fused alumina with higher hardness is used by some high-end users, because it has better cutting force and good polishing, and is mostly used for carbon steel, alloy steel, forged steel, hard bronze, etc. Use white fused alumina to grind more finely and brightly,
The brown fused alumina is used in a relatively large market, and it is mostly used for quenched steel, high-speed steel, and high-carbon steel to remove burrs on the surface, and the grinding effect is not as bright as that of white fused alumina.
