Technical Products, Inc.

Alumina Ceramic Grades 96%-99.99% Manufacturing

Technical Products, Inc. is a global manufacturer and distributor of industrial ceramics. TPI has a large supply of Alumina in various grades, sizes, and shapes including substrates. Our knowledgeable Alumina department is able to provide guidance on choosing the materials that will best fit your applications.

Alumina

Alumina Oxide is a readily available material with reasonable cost possessing excellent properties handling thermal and mechanical shock. It is fabricated and used in a wide range of applications from stock to tight tolerance machined parts and laser machining of Alumina substrates. TPI presses Al2O3 ceramics from 96% up to 99.99% purity. See below the stock sizes available order on line.

Our processes include cold isostatic pressing of green billets, pre-fired machining, sintering, and post sintered grinding operations. Technical Products, Inc. not only machines high purity Alumina ceramics but has an on-site heat treat department for all ceramic firing applications. Al2O3 ceramics may become dirty through handling, machining or inspecting a "clean fire" is performed to burn off all surface contaminants.

Alumina Substrates are engineered to minimize as-fired resistor variations and maximize aged adhension values. Superior resistor stability is achieved by controlling the substrates effects on the temperature coefficient of resistance. Alumina Substrates are particularly well suited for small geometry, high resistor value circuitry.
