Granex

Granex is a type of abrasive grain primarily composed of aluminum oxide. It is manufactured through a high-temperature fusion process, resulting in a hard, durable, and sharp abrasive material. This makes Granex suitable for a variety of grinding, cutting, and polishing applications. Its crystalline structure provides good toughness and wear resistance, allowing it to maintain its abrasive properties over extended use.

The manufacturing process for Granex typically involves melting bauxite ore in an electric arc furnace. The molten material is then cooled and crushed into various grit sizes, depending on the intended application. These grit sizes range from coarse for heavy material removal to very fine for achieving smooth finishes. Granex is widely used in the production of coated abrasives, such as sandpaper, and in bonded abrasives, like grinding wheels and abrasive powders. Its versatility and cost-effectiveness have made it a staple in industries ranging from metalworking and woodworking to automotive and aerospace.
