Mingrui high temperature ceramic furnace tube are 99.5% to 99.8% high purity and offer elevated temperature stability. Alumina tubes are available in custom sizes, including American and Metric, and offer a low material cost.
Minerals containing alumina make up nearly 15% of the earth’s crust. This makes it practically inexhaustible and versatile. Alumina provides the combination of low thermal expansion, superior thermal conductivity and high compressive strength making it thermal shock resistant and the ideal product for alumina tubes. Our alumina tube models have elevated dielectric properties and are gas tight providing a higher vacuum or protective atmosphere when at an extreme temperature.
These high temperature ceramic tube offer:
