Polycrystalline corundum

Polycrystalline corundum
Polycrystalline corundum is produced by adding new elements to the black corundum manufacturing process, thereby optimizing its primary crystal structure. It exhibits a brown‑black color and is characterized by high hardness, excellent toughness, and superior self‑sharpening properties. Polycrystalline corundum retains the advantageous features of black corundum—such as outstanding self‑sharpening, exceptional sharpness, low heat generation, and a highly polished surface—while significantly enhancing its durability.
