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:
1. What kind of industry ceramics do you have?
We specialized in 95% 97% 99% alumina ceramic and zirconia ceramic parts.
2. What kind of molding method can you supply?
Dry Pressing, isostatic pressing, grouting, hot-chamber die casting, tape casting, injection molding, etc, injection molding and isostatic molding is the most commonly used.
3.What stabilizer do you use when processing?
Yttria stabilizer is the most commonly used in our industrial ceramic parts.
4.Can you produce free samples for me?
Yes usually, we can produce free samples for you but it is up to the product complexity .
5.What terms can you accept for payment?
T/T, L/C , Western union , Money Gram and Paypal is welcome , but paypal and western union only for small-sum payment.
