What is rust metal or non-metal

Remove pink aluminum oxide rust FEPA F8-220 metal and non-metal parts

Product description

Pink fused alumina

Pink fused alumina, also called aluminum oxide Pink Fused, chromium aluminum oxide, abbreviated as "PA",

belongs to the group of artificial corundum. It made of the fusion of high purity alumina powder and chromium oxide

in the electric arc furnace. Because of its chromium content, it is a pink color material.

Compared with white fused alumina, it has similar hardness while better strength and cut side. It is

Widely used in the production of the vitrified grinding wheel, resinous grinding wheel, cutting disk, grinding head and other

Abrasive tools, also for sandblasting, cutting abrasvies, polishing, free rubbing, etc.
