- In some medical or bioengineering applications, specific grades of Alumina Ceramics are biocompatible, making them suitable for use in medical implants or devices.

These characteristics collectively make alumina ceramic shaft bearings valuable in industries such as aerospace, automotive, medical, and others where reliability, precision, and resistance to wear are critical for efficient and long-lasting performance.

We offer ceramic parts made of alumina with the  purity from 95% and 99.8% (NON-POROUS). High purity Alumina Ceramics are particularly suitable for applications where the working enviroments have very strict requirment about  abrasion or corrosion resistance. And due to its excellent thermal stability (stable chemical properties and low thermal expansion), alumina ceramics can be used in an environment that temperature drastic changes.
