Brown Fused Alumina BFA Abrasives

Which one is better, brown aluminum oxide or white aluminum oxide ?

Brown corundum and white corundum each have their own advantages and disadvantages and are suitable for different occasions and uses. The choice of abrasive depends on the specific machining needs and application scenario. The following is a detailed introduction to brown fused alumina and white fused alumina: 

Brown corundum, it has high hardness and strong grinding ability, and is suitable for processing metal materials with high hardness, such as stainless steel, carbon steel, etc. It is often used to make grinding tools such as grinding wheels, abrasive belts, and whetstones, as well as sandblasting metal surfaces. It is suitable for grinding high-hardness steel and cast iron parts. 
White corundum, it has good toughness and chemical stability, and is suitable for processing materials with low hardness or high surface roughness requirements, such as aluminum alloys, copper alloys, etc. Suitable for manufacturing fine abrasives and abrasives, suitable for grinding materials such as aluminum alloys, non-ferrous metals and optical glass, and also used for polishing high-precision parts and optical lenses.

In general, brown fused aluminum oxide is a better choice if it needs to be used in high-intensity and heavy-load wear environments. If you need to use high-precision and high-gloss materials, white fused aluminum oxide is more suitable.
