Frequently Asked Questions

What is the difference between White Fused Alumina and Brown Fused Alumina?

White Fused Alumina (WFA) is made from high-purity alumina and has over 99% Al₂O₃ content, offering higher hardness and whiteness. Brown Fused Alumina (BFA) contains iron and titanium impurities, giving it a brown color and slightly lower hardness, but excellent toughness for abrasive applications.

Can you customize particle size distributions?

Yes, we offer custom sizing from coarse grits to fine powders (F8 to F220 and beyond). We can also provide specific D50 values and narrow distribution ranges upon request.

Are your products suitable for refractory castables?

Absolutely. Our White Fused Alumina, Tabular Alumina, and Fused Spinel are widely used in high-alumina castables for cement kilns, steel ladles, and industrial furnaces due to their high refractoriness and thermal shock resistance.

Do you provide samples?

Yes, we offer free samples for qualified buyers. Please contact us with your requirements and shipping details.
