1. Color: White fused alumina has a higher alumina content than brown fused alumina, so the former is white, while the latter is brown.

2. Raw materials: The raw materials for brown fused alumina are anthracite, iron filings, and bauxite, while the white fused alumina is alumina powder. White fused alumina is used for ordinary grinding of hard alloy copper, high-speed copper, and quenched copper workpieces, as well as for gear grinding, thread grinding, and forming grinding. Brown fused alumina has high toughness and is suitable for grinding metals with high tensile strength such as ordinary steel, malleable cast iron, and hard bronze. It can also be used to manufacture refractory materials.

3. Hardness: The hardness of white fused alumina is higher than that of brown fused alumina. White fused alumina is a crystalline compound with better hardness and toughness, small crystal size, and good wear resistance, but it has high production cost and low yield. Brown fused alumina has moderate hardness, weak grinding effect, and relatively low price.
