▼ Material Introduction


Alumina ceramic is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Ceramic bars made of alumina are used in a wide range of applications such as electronics, pump components and automotive sensors. Alumina ceramic bars can be formed by a variety of manufacturing techniques such as uniaxial pressing, isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining and a variety of other processes. UNIPRETEC offers a variety of alumina ceramic compositions with Al2O3 purity range from 90% to 99.8%.
