Chrome Coated Green Aluminium Oxide Grains WFA 99% For Resin Cutting Disc
Chrome Coated White Fused Aluminum Oxide WFA99% for Resin Cutting Disc
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. White fused alumina is suitable for use as an iron-free fine blasting agent for applications in the aluminium, optical and dental industries and for demanding applications in the blasting agent and refractory industries. Thanks to its transparency and abrasion strength, prime-quality white fused alumina is contained in resins and varnishes and therefore is used in the varnish, laminate and surface-treatment industries.
