Product detail
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 hardness, high strength, low dielectric constant and dielectric loss, good wear resistance, high temperature resistance and corrosion resistance. It is the one of the most hard and wear resistant materials on the earth and can only be machined using diamond-grinding methods after sintering.
The applied fields of alumina ceramic is very wide, including machinery, electrical, electronics, semiconductor, petroleum, chemical, textile and other industries, it is suitable for purpose of wear resistance, high temperature, electrical insulation, corrosion resistance. Mascera can provides alumina ceramic in purities 95%, 96%, 99%, 99.5%, 99.8% etc, the higher purity have enhanced higher working temperature, strength, wear and corrosion resistance. We are able to make alumina ceramic parts in custom size and shapes, we have good capability to manufacture ceramic parts in different molding methods and make high precision machining on sintering parts , welcome to contact us whenever you have demands.
