Description:
Pink Fused Alumina is electrically fused in high temperature, being added with the right quantity of oxidized chromium. It is pink. Its hardness is close to, but toughness higher than that of WA. 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.
Usage:
1.pink fused alumina is generally for hardened steel, alloy steel armor and workpiece grinding.
2.pink fused alumina is suitable for precision grinding of measuring and instrumentation components.
3.pink fused alumina is also suitable for form-products grinding.
