2rd Grade Brown Fused Alumina Blasting Media

We all know that 95% brown fused alumina can be used in sandblasting process. Besides, 95% Alumina, Yannuo also produce 85% alumina for sandblasting application. And the chemical index of 2rd grade brown fused alumina is attached as follows.

Compared with first grade brown fused alumina blasting media, second grade brown fused alumina has lower Al2O3 content, and higher impurity impurities of Fe2O3, SiO2 and TiO2..The recycle rate of 2rd grade brown fused alumina is 60-70%. It can be used in blasting and derusting, but its not suitable for the blasting in the process precision of workpieces.
