Mingrui alumina tubes 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 alumina tubes offer:
- Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800°C.
- Extreme wear and abrasion resistance.
- Chemical corrosion resistance under high temperature.
- High dielectric properties.
- Gas tight for many applications to provide protective atmospheres or high vacuum at high temperature to eliminate contamination or impurity.
- Low material cost and custom size available.
- Available Tube Diameter From 3/16″ to 9″ for American size and 2 mm to 150 mm.
- Available Tube Length: From 1″ ( 25mm) To 72″ ( 1828mm).
- Most items are in Stock and can be delivered in 1-3 days.
- Sentro Tech also offer volume discount for all listed sizes if order quantity is more than 5 pieces for same size
