Pink Fused Alumina

PRODUCTS DESCRIPTION

Pink fused alumina, also called chromium fused alumina, is a kind of alumina with little Cr2O3. Compared with brown fused alumina, pink fused aluminium oxide has a higher hardness and lower toughness.

Application:

  • Pink fused aluminium oxide abrasive tools are suitable for grinding high carbon, high-speed steel and thin-walled components etc.
  • Pink fused aluminium oxide is suitable for precise grinding of measuring tools, machine shift, instruments and apparatus parts, threading workpieces etc.
  • Pink fused aluminium oxide also can be used as polishing, precision casting, spraying and refractory materials.
