Discription
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.

Application
Residual removal for various work pieces surface
Pipeline cleaning
Hull de-rust
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.
