Brown fused alumina  VS White Fused Alumina for Sandblasting Applications

BFA is abbreviation of Brown Fused Alumina(Brown Fused Aluminium Oxide, Brown Aluminum Oxide, Brown Corundum) and WFA/WA is abbreviation of White Fused Alumina(White Fused Aluminium Oxide, White Aluminum Oxide, White Corundum). These two abrasives are both good media for sandblasting applications.

For Mohs’Scale of Hardness, it’s 9.0 and 9.5 for Brown Aluminium Oxide and White Aluminium Oxide separately. Both BFA and WFA are prefect media for sandblasting without air pollution

  • Brown Aluminium Oxide is better for ordinary sandblasting because of cost advantage. White Aluminium Oxide is high purity and white color, it is better for sandblasting special products with magnetic property and demanding color requirement

  • According to application experience, BFA F16-F46 are mostly used for ship body and oil pipeline because surface smoothness is not the biggest concern for these products

  • Precision products, including mobile shell, computer cover and some stainless steel device, have demanding requirements for color, surface status, further painting after sandblasting, so White Aluminium Oxide F60-F220 are mostly used for this application.
