China ceramic substrate alumina substrate al2O3 substrate aluminum oxide substra

Alumina plates are made of alumina ceramics. Aluminum oxide is a ceramic material with high thermal conductivity, compressive strength, and resistance to thermal shock. It also has low thermal expansion, making it a furnace material in the form of crucibles, tubes, and thermocouple sheaths. Alumina ceramic plates can withstand high temperatures and maintain high strength and hardness. Alumina ceramic plates also have excellent electrical insulation properties, high chemical and cold heat resistance, and low thermal expansion. We stock semi-finished shapes in various sizes and are capable of custom fabrication for various alumina components.
