Brown Fused Alumina Types for Abrasives & Refractory Use

What is Brown Fused Alumina (BFA)?

Brown Fused Alumina (BFA), also known as Brown Corundum, is a tough, hard abrasive made by fusing bauxite and carbon in electric arc furnaces. It is widely used for abrasive blasting, bonded abrasives, coated abrasives, and refractory materials due to its high thermal resistance and mechanical strength.

Frequently Asked Questions About Brown Fused Alumina

Everything you need to know before sourcing BFA for your abrasive, refractory, or surface treatment needs.

Brown Fused Alumina (BFA) is a high-hardness abrasive material produced by melting calcined bauxite in an electric arc furnace above 2000°C. It’s composed primarily of Al₂O₃ with minor iron oxide and TiO₂, making it ideal for grinding, blasting, and high-heat applications.

BFA is commonly used in bonded and coated abrasives (grinding wheels, sandpaper), blasting media, refractory bricks, non-slip flooring, and precision ceramics due to its toughness, thermal stability, and chemical resistance.

Coarse grits (F8–F36) are used for heavy grinding and cutting. Medium grits (F40–F80) balance aggressiveness and finish. Fine grits (F90–F220) are for polishing and light finishing, while micro powders (F240–F1200) suit ultra-fine precision polishing. Contact us to match grit to your application.

We deliver consistent quality through strict control of chemistry and grain shape. Our ISO-certified process ensures low impurity levels, uniform hardness, and reliable performance. We also offer customization, fast lead times, and full technical support.

Yes. We can produce custom grit size distributions, adjust chemistry within spec ranges, and provide private-label or special packaging. Let us know your technical specs and we’ll develop a solution tailored to your process.
