 	<li>1.Raw materials: The raw materials of <a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html">brown corundum</a> are bauxite, in addition to anthracite and iron. The raw material of <a href="https://www.xinliabrasive.com/White-Fused-Alumina.html">white corundum</a> is alumina powder.</li>
 	<li></li>
 	<li>2.Uses: Brown corundum can be used to manufacture ceramic and resin high-bonded abrasive tools, as well as grinding, polishing, sandblasting, precision casting, etc., and can also be used to manufacture advanced refractory materials. White corundum is suitable for grinding fine-grained abrasives such as high carbon steel, high-speed steel and stainless steel. White corundum can also be used for precision casting and advanced refractory materials</li>
 	<li></li>
 	<li>3.Performance: <a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html">Brown corundum</a> has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. White corundum has the characteristics of high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. In comparison, the hardness of white corundum is higher than that of brown corundum.</li>
 	<li></li>
 	<li>4.Composition: Although both brown corundum and white corundum contain alumina, the alumina content of white corundum is above 99%, and the alumina content of brown corundum is about 95%.</li>
 	<li>5.Color: Because the alumina content of white corundum is higher than that of brown corundum, the color of white corundum is white, and the brown corundum is brown-black.</li>
 	<li></li>
 	<li>6.Production: <a href="https://www.xinliabrasive.com/White-Fused-Alumina.html">White corundum</a> is produced from alumina powder (the same raw material used for electrolytic aluminum), while brown corundum is produced from calcined bauxite.</li>
 	<li></li>
 	<li>7.Application: White corundum is used by some high-end users because it has good cutting force and good polishing effect. It is mostly used in carbon steel, alloy steel, malleable cast iron, hard bronze, etc., while <a href="https://www.xinliabrasive.com/Brown-Fused-Alumina.html">brown corundum</a> is commonly used in the market. It is also used in a relatively large amount in the market, and is mostly used for quenched steel, high-speed steel, high-carbon steel, etc.</li>

 	<li><a href="https://www.xinliabrasive.com/White-Fused-Alumina.html">White corundum</a> has strong cutting force and is used to remove metal or non-metal burrs, pre-batch burrs, etc. It has the function of polishing the surface of parts and belongs to the medium polishing abrasive. Brown corundum is used to remove the surface burrs of stainless steel, carbon steel, aluminum alloy and other hardware parts. The grinding of brown corundum is not as fine and bright as white corundum.</li>
