Mean diameter of Pink Fused Alumina PFA

Pink fused alumina PFA  is also called pink corundum and pink aluminum oxide,short for PFA or PA.

Pink fused alumina is obtained by adding chromium oxide to aluminum oxide during the fusion process.

Zhengzhou haixu abrasives co.,ltd,founded in 1999 from China,has been manufacturing and exporting pink fused alumina for more than 20years.

Divided by the purity of Cr2O3,our factory have three kinds which called Low Chromium( 0.2-0.45% Cr2O3),Medium Chromium(0.45-1% Cr2O3) and high Chromium(1.0-2.0% Cr2O3).

About the sizes,we mainly produce the macrogrit under JIS standard and FEPA standard separately,and the mean diameter of its size is as follows:
