Abrasive Belt (XAD011)

A sanding belt is an abrasive coated tool consisting of a flexible substrate—such as paper or cloth—bonded to abrasive grains with an adhesive. It is primarily used for grinding and polishing metals, wood, plastics, and other materials. Its core structure comprises a substrate, abrasive grains, and an adhesive, offering excellent adaptability and high safety.

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.

Black Corundum

Black corundum is an energy‑saving, environmentally friendly alternative wear‑resistant material produced by high‑temperature smelting in an electric arc furnace, using high‑iron alumina or high‑alumina bauxite combined with high‑alumina iron ore. After melting and subsequent cooling, it yields a gray‑black crystalline product whose principal mineral phases are α‑Al₂O₃ and ferrospinel.

Black silicon carbide

Black silicon carbide is produced by high‑temperature smelting in an electric resistance furnace, using raw materials such as quartz sand and petroleum coke (or coal coke). Due to its stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and excellent wear resistance, silicon carbide is used not only as an abrasive but also as a refractory material.
