Brown fused alumina is a tough, long-lasting material. Its color is brown because its impurity level is slightly higher than that of white corundum. With a Mohs hardness of 9, brown corundum is a high-strength wear-resistant material with the ability to resist strong chemical attack (such as acids and alkalis) at extreme temperatures. Typical applications for brown corundum include sandblasting and grinding.
Henan Qingjiang Industrial Co., Ltd. provides standard FEPA grade brown corundum.
