Brown Fused Alumina for Precision Polishing

Consistent particle control and cutting performance for fine surface finishing in demanding applications.

Brown fused alumina used in precision polishing

Why Use BFA in Precision Polishing?

Brown fused alumina (BFA) is ideal for polishing applications requiring fine control of surface roughness and material removal. Its blocky grain shape and high Mohs hardness (9.0) ensure a balance of durability and cutting action, while its recyclability makes it cost-effective for repeat use in polishing systems.

  • Sharp, angular grains for predictable cutting
  • Low contamination risk in surface-sensitive applications
  • Uniform particle distribution for mirror-finish polishing

Common Polishing Applications

  • Tool and die finishing in mold shops
  • Optical lens surface preparation
  • Medical implants and surgical tool polishing
  • Precision components in aerospace and defense

Suitable for use in both dry and slurry-based polishing systems.

Recommended Grain Sizes

  • Fine lapping & pre-polish: F220–F400
  • Precision polishing: F600–F1000
  • Ultra-fine finishing: F1200 and micro-sized fractions

Available in narrow PSD distributions with custom screening or micronization upon request.
