95 99 99.5 Al2O3 Alumina Ceramic Rods

Alumina ceramic is also called al2o3 ceramic or aluminum oxide ceramic, is one of the most widely used technical ceramic materials. Alumina ceramic has a series of advantages such as high strength, good dielectric properties, excellent wear resistance, high temperature resistance and corrosion resistance. It is one of the most hard and wear resistant materials on the earth and can only be machined using diamond tools after sintering. The applied fields of alumina ceramic is very wide, including machinery, electrical, electronics, semiconductor, petroleum, chemical, textile and other industries etc.

Mascera offers tailor-made alumina ceramic rods in a wide range of purities, 95%, 96%, 99%, 99.5%, 99.8%. The surface finish of alumina ceramic rods can be as fired, fine grinding or polishing, the geometry can be machined into tight tolerance to meet high fitting requirements. Besides, thread can be machined on the both ends of alumina ceramic rods for fastening purpose. No matter small quantity for prototype or big quantity for batch production, we are always ready to provide our service.
