Pink Fused Alumina

Description:

Pink Fused Alumina, also called Pink Fused Aluminum Oxide, Chromium Aluminum Oxide, or ruby fused alumina, abbreviated as "PA". It is a kind of artificial corundum produced by adding chromium oxide to high purity aluminum oxide during the fusion process to get a pink color alumina. The amount of chromium oxide added affects the color of the final product, as well as the toughness of the grain. With increased additions of Cr2O3 to Al2O3,toughness and self-sharpening ability get increased and friability get decreased comparing with white alumina. So it can well balance the sharpness and life time with applications.

Defined with chromium oxide percentage, HAIXU Abrasives provide 3 types: Low chromium PA, Medium chromium PA, high chromium PA.

Characteristic:

  1. Pink Fused Alumina is a kind      of pure abrasive (Al2O3 purity 96.5-99%)

  2. High toughness and      self-sharpening

  3. High hardness with sharp      edges of crystals.

  4. Durable, hard and resists      high pressure

  5. High abrasive resistance

  6. It does not contain iron      under normal conditions

  7. It has a structure suitable      for wet and dry sandblasting applications

Applications

1.      Precision bonded abrasive tools include resin bonded abrasive and vitrified abrasive tools

2.      For the gentle cleaning, deburring, roughening and matting of high grade metallic or austenitic materials

3.      Sandblasting, rust removal with aggressive blasting is requires

4.      Sandblasting clean before Teflon and coating

5.      Lathe main shafts

6.      Lapping ,polishing for extreme hard materials

7.      Mainly used in sensitive areas of the aviation and space industry and in reactor construction

8.      Instruments and apparatus parts

9.      Threading workpieces

10.   Samplers
