product description

Pink Alumina (PA)

  Pink alumina, its hardness is close, but the toughness is higher than WA. The grinding tool made of it has excellent durability and high processing cleanliness. Precision grinding machine spindles, instrument parts, threaded workpieces and sample grinding.

  Chrome corundum, chrome corundum abrasive, chrome steel jade powder (PA) chrome steel jade, chrome corundum micropowder is the main raw material of alumina powder, adapted to chrome oxide, etc., and is smelted at high temperature.

  1.Chromium corundum powder/chrome corundum is made of alumina as the main raw material, and is suitable for chromium oxide.

  2.Made by high temperature melting.

  3.It is pink, hardness is similar to white corundum, and toughness is higher than white corundum

  4.Instrument, gage and low roughness surface

  5. Fine research
