PINK FUSED ALUMINA F#70MESH 250-212MICRONS
Pink fused alumina is also called pink aluminum oxide,pink corundum,pink fused aluminum oxide,pink electrocorundum,chromic fused alumina,for short”PFA” or “PA”.
It is obtained by adding chromium oxide to aluminum oxide during the fusion process.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been producing and exporting pink fused alumina for more than 20years.we mainly produce the following sizes:
| For abrasive | F12 F14 F16 F20 F22 F24 F30 F36 F40 F46 F54 F60 F70 F80 F90 F100 F120 F150 F180 F220 #12 #14 #16 #20 #24 #30 #36 #40 #46 #54 #60 #70 #80 #90 #100 #120 #150 #180 #220 |
