• White fused alumina

White fused alumina

White corundum is made under high temperature conditions above 2000 degrees. Through multiple processes including crushing, shaping and sieving, it excels in appearance and hardness as a widely used special material. White corundum is not only high in hardness, but also brittle in texture, strong in cutting power. It also performs well in insulation, self-sharpening, wear resistance and thermal conductivity. Meanwhile, it is resistant to acid and alkali corrosion and high temperature. Therefore, as a super hard material, white corundum possesses very excellent properties.
