Products Advantages

(1) High strength: Brown corundum has high hardness, high density, high hot and cold strength, etc., and has better wear resistance and corrosion resistance in harsh environments such as high temperature and thermal stress;

(2) Acid and alkali corrosion resistance: Brown corundum performs relatively well in strong acid and alkali corrosion environments;

(3) High temperature resistance: Brown corundum has a high melting point, maintains high temperature for a long time, and is not easy to melt;

(4) Excellent chemical stability: Brown corundum reacts less with various metals and compounds and is an ideal dielectric material;

(5) Uniform particle size distribution: The particle size distribution of brown corundum is uniform, making it approximately equal-diameter spherical, and has excellent performance in wear resistance, corrosion resistance and high temperature performance;

(6) High purity: The high purity and chemical stability of brown corundum can ensure that it is harmless to humans and nature.

(7) Wear resistance: Brown corundum has high hardness, strong wear resistance, uniform particle size and smooth surface;
