Pink fused alumina with high quality manufacturer

Specifications
1 Al2O3:98.0%min
2 Good Hardness and Toughness
3 Verified by ISO9001

1.Introduction
1）Pink fused alumina is produced by adding with the right quantity of oxidized chromium.
2）It has more toughness and less friability, compared with white fused alumina.
3）The abrasive tools made of it feature excellent durability and high processing cleanness, which are suitable for the precision grinding of the measuring tolls, lathe main shafts, instruments and apparatus parts, threading work pieces and samplers, etc.
