Green Abrasive Aluminum Oxide Grits Chrome Coated For Grinding Wheels
Chrome Coated White Fused Aluminum Oxide WFA99% for Vitrified Bonded Abrasives
1. White Fused Alumina Descriptions
Coated white fused alumina is made of high-qality white fused alumina as the raw material and plate iron oxide or other material on the surface of abrasive during high temperature treatment. WFA is a fused white alumina abrasive powder produced by crushing fused alumina and sorting the particles into a uniform size.
