Alumina BushingAlumina Bushing Description

Alumina Bushing 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.

Alumina Bushing Applications

Aluminum oxide bushing can be 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.
• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
• Used as protector for high temperature thermal couples.
• Used as a material for chemical industry due to its high corrosion resistance.

Packaging

Our high quality alumina ceramic bushing is carefully handled to prevent damage during storage and transportation and to preserve the quality of our product in its original condition.

Nice Product

I used these in a drill, didn't have air handy for the angle grinder, so didn't get the best out of them but they held up well in the process of cleaning up cast iron pan to reseason and use! They lasted longer than I had expected, will by from the company again for other metal projects!
