Calcined Brown Fused Alumina For Coated Abrasives
Informação de produto geral
Calcined Brown Fused Alumina specially used for coated abrasives1. Introduction
It is a kind of BFA treated with high *ugh calcination, the impurities are precipitated or vaporized out of the abrasive. So the surface is more pure and rough. And the hydrophilicity and strength are raised greatly as the invisible damages closed. Color changes from brown to blue. We are quality supplier and long-term partner of Saint-Gobain in this product. The annual output is 8000 tons.
