Alumina Ceramics Thermocouple tube
My factory looking for distributors.
Alumina ceramics have good mechanical strength, conductivity and high temperature resistance. In fact, alumina ceramics are the most widely used ceramics. Because it is very superior in performance, it is more and more widely used in the current market. It can not only effectively meet the daily use, but also meet some special needs.
Alumina ceramics are also divided into different types. Among them, 99.7% alumina ceramics are made of high-purity alumina materials, coupled with a series of related strict process guarantees, and the performance is more superior. Compared with 99% alumina and 95% oxidation Aluminum has higher density and higher bending strength.

Alumina purity test report
RFQ
1.What are the benefits of alumina ceramics?
Alumina ceramics is a widely used material because it can be produced in a range of purities—from 85 to 99.9 percent pure—that provide unique benefits. Generally, alumina ceramic components offer quality strength, hardness, corrosion resistance, and thermal stability.
2.What is the temperature rating of alumina ceramic?
Alumina is often used as a replacement for metallic components in demanding engineering applications. IPS Ceramics supply 95% alumina for applications below 1450 ºC / 2650 °F and 99% alumina for temperatures up to 1600 ºC / 2900 °F or where contamination of the sample must be avoided.
3.What is the disadvantage of alumina?
Alumina shares several characteristics with other polycrystalline ceramic materials, such as moderate tensile and bending resistance and the brittle fracture behavior, which is the main disadvantage of the mechanical properties of alumina.
