Industrial Custom High-Temperature Wear Resistance Insulation Steatite 95% 99% Al2O3 Alumina Electrical Ceramic Parts

Product Description

Custom High-temperature Wear Resistance Insulating Steatite Al2O3 Alumina Electrical Ceramic Parts
 

Product Description

Custom alumina (Al2O3) parts are made out of high-purity aluminum oxide ceramic. This engineered ceramic owns excellent high-voltage electrical insulation, high-temperature resistance, remarkable abrasive resistance as well as high thermal conductivity and low thermal expansion. Aluminum oxide ceramic is one of the most cost-effective materials in the entire advanced ceramic family which has obvious cost and performance than other ones. Therefore, alumina ceramic parts have been extensively used as electrical insulators, thermocouple sheaths, holders, and wear components, grinding media in electrical appliances, electronics, textile machinery, and semiconductor industries.

Our facility offers rigorously selected optional purities of alumina, mainly including 95%, 99%, 99.5%, and 99.7%. Our integrated manufacturing capability ensures we achieve various complicated configurations of ceramic parts, also it could help us complete the quick prototyping to mass production run. In addition, we can achieve precision grinding and CNC machining in-house which enables us to provide one-stop service to our esteemed partners.
