Product Description

Product Description

The alumina plate is made of aluminum oxide ceramics. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Aluminum oxide ceramic plates can withstand high temperatures and maintain high strength and hardness. Alumina ceramic plates also have superb performance in electrical insulation, high chemical resistance, good heat resistance, and low thermal expansion. We have various sizes of semi-finished shapes in stock and can conduct custom manufacturing for all kinds of alumina components.
