Alumina complex shapes are a group of aluminum oxide ceramic products. 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 crucible, tube, and thermocouple sheath form. Alumina is high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metallizing.

Alumina Al2O3 complex shapes are used in the following applications:
• Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles and insulators.
• Alumina tubes are widely used as protector for high temperature thermal couples.
Our Alumina complex shapes are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
