Black Aluminum oxide blasting media F12#-400# Al2O3 62% Min.
Black aluminum oxide is a new type of sandblasting and polishing
media. It is made of trihydrate and boehmitic bauxite as raw
materials by arc furnace smelting and cooling process. The black
aluminum oxide abrasive has concentrated basic grits distribution
and good toughness.
The production process determines that the power consumption is
lower than that of brown fused alumina, and the emissions are less.
It is an environmentally friendly and cost-effective abrasive
product.
Mainly used for blasting and polishing for stainless steel, metal
products, optical glass, bamboo and wood products, and also a new
abrasive to manufacture bonded abrasives grinding wheels, cutting
sheets and abrasive sand paper.

Higher cost effective to replace of brown fused alumina
Especially for stainless steel work piece polishing with unique
advantage because of
its moderate hardness and good toughness
It is also possible to combine black fused alumina with other
abrasives of higher hardness
and better wear resistance like brown fused alumina to make
polishing abrasives such as
polishing wheels, fiber wheels and abrasive belts.
The effect is better than using black fused alumina only or simply
using other single abrasive.
better grinding and polishing effect, higher cost performance.
