Introduction of Alumina Ceramic Ring
Alumina ceramic rings are round ceramics made from 氧化铝（Al2O3） through various processing techniques. Our Alumina ring has super high wear resistance and corrosion resistance.
We provide customized services for you based on the drawings you provide. During the customization process, we have a professional team to solve your doubts 24 hours a day. The process of customizing products is transparent and visible. If you have any needs, we can report the customization progress to you in real time.
If you need to customize high-quality Alumina rings, please be sure to contact us. We can provide you with a different service experience.
Superior Production Technology of Alumina Rings
We pay attention to the processing of products, and we strive for perfection in every processing step.
In the process of processing alumina ceramic rings, we grind alumina into submicron (nano) level powder. After actual measurement, the particle size of alumina after sintering can be less than 5 microns. Alumina ceramic rings are composed of these tiny particles. There are almost no pores in the ceramics we produce, and the density is about 3.9 克/厘米3 , which creates excellent mechanical strength of alumina rings.
Usage Classification of Alumina Rings
There are many types of alumina ceramic rings, which are more specifically divided into sealing rings, insulation rings, wear-resistant rings, support rings, etc.
🔷 Sealing ring: Sealing ring is mainly used in equipment that requires tight sealing. Our alumina ceramic ring is resistant to high temperature (withstanding high temperature above 1600℃), with simple appearance design and excellent sealing effect, which can keep your equipment in a tight sealing environment.
🔷 Insulating ring: Alumina has excellent electrical insulation. Our alumina insulating ring is designed with special cuts and functions, which can be cut into suitable equipment, provide excellent electrical insulation performance, effectively prevent current leakage, and protect your electrical equipment.
🔷 Wear-resistant ring: The biggest feature of alumina wear-resistant ring is high hardness and strong wear resistance (alumina has a hardness comparable to diamond). The alumina wear-resistant ring we produce can be used in various harsh high-wear environments with confidence.
🔷 Support ring: Support rings usually have unique shapes and some special additional structures. The additional structure can provide good support. Our alumina support rings can be well used in machinery or support structures.
How to Choose Alumina Ring with Appropriate Purity
Normally, the higher the purity, the better the performance of the alumina ring,The common alumina purity range is 92~99.9. We can customize alumina ceramics of various purity and sizes for you.
- 95% alumina rings have low cost, moderate hardness and strength, and are suitable for medium-strength scenarios, such as general wear-resistant parts.
- 99% alumina rings have a high hardness and can be used in higher-intensity application scenarios, such as chemical equipment that requires little chemical corrosion, or electronic devices and high-temperature furnaces.
- Alumina ceramics with 99.5% or above have extremely high hardness and strength, as well as excellent electrical insulation and high temperature resistance. Can be used in high-end electronic devices and precision medical equipment.
- Ultra-pure alumina is an alumina ceramic with a purity >99.9%. This ceramic has almost no impurities and has excellent mechanical properties and chemical stability. It is used for high-end technology research and scientific experiments, such as semiconductors, optical instruments and nuclear industrial manufacturing.
