<p id="cs"><a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html"><strong>Brown fused alumina</strong></a>, also known as brown corundum, has different quality levels– the first level brown fused alumina and the second level brown fused alumina.</p>
<br class="break/">
<p id="cs">The levels of <a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html"><strong>brown fused alumina</strong></a> mainly depend on the content of Al2O3, which is the main component of brown fused alumina. First level brown fused alumina has 94-95% Al2O3. Second level brown fused alumina has only 88-91%Al2O3.</p>
<p id="cs">Besides, the main usage of these two levels <a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html"><strong>brown fused alumina</strong></a> is also different. First level brown fused alumina is mainly used for grinding and polishing, precision casting. Besides, 20#, 24#, 30#, 36#. 40# and 46# first level brown fused alumina is specially used for grinding wheels. However, the main application for second brown fused alumina is sandblasting.</p>
<p id="cs">All in all, please pay more attention to Al2O3 content when you use <strong><a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html">brown fused alumina</a></strong> for different situations.</p>
