Semi-Friable Alumina

Semi-Friable Alumina is a fused synthetic abrasive made from high-grade calcined alumina combined with controlled additives. It offers a balanced combination of hardness and friability, making it tougher than white fused alumina but more friable than brown fused alumina. This allows for controlled grain breakdown, delivering efficient cutting action with extended wheel life. Semi-friable alumina is ideal for precision grinding applications in bonded abrasives, as well as refractory uses that demand good thermal stability, strength, and resistance to thermal shock.
