Frequently Asked Questions

Get answers to common inquiries about our products and services.

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

Brown Fused Alumina (BFA) is made from bauxite and has a lower Al₂O₃ content (94-96%), making it tougher and ideal for heavy grinding. White Fused Alumina (WFA) is made from calcined alumina with >99% purity, offering higher hardness and used in precision applications.
