Multi-bore Alumina Tube Description

alumina tubeAlumina 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. 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 metalizing.

Multi-bore Alumina Tube Applications 

• Air, gas and liquid filtration
• 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 a protector for high-temperature thermal couples.
at high temperatures.
• Used as the protector for high-temperature thermal couples.
• Used as a material for the chemical industry due to its high corrosion resistance.

Packaging

Our Alumina tubes are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
