BFA Macro Bonded Vitrified
BFA Macro Bonded Vitrified
Descriptions
Kowa’s Brown Grits for Vitrified Abrasive wheel is a very tough brown fused aluminum oxide abrasive with medium titania, blocky shape and high density. To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes. It is used for making vitrified bonded abrasive products where the very tough, strong aluminum oxide is required.
Applications
It is used for making vitrified bonded grinding wheels, cut-off wheels. The tough, strong aluminum oxide characteristic also enable this abrasive the used for pressure blasting and surface finish.
