Product Description

Customized Industrial High Precision Technical High Hardness OEM Wearable Electrical Insulation Ceramic Parts  Al2O3 Plate 99% 99.5% 99.7% C799 Alumina Ceramics

Product Description

The main characteristics of the alumina ceramic parts

1. High hardness,  up to 1700 HV

2. High heat resistance, up to 2000ºC in the vacuum atmosphere

3. Good wear resistance, much better than additional metals

4. High electrical resistivity, suitable for a variety of high-voltage, high current applications

5. High corrosion resistance, can be used in various strong acids and alkalis.

6. They offer different grade dimensional accuracy per sintered only, precision machining 

7. We support a variety of customized alumina ceramic parts 

The description of alumina ceramic parts
Alumina  (Aluminum oxide)  offers excellent electrical insulation, high-temperature resistance together with high hardness and good wear resistance, so alumina ceramic parts are commonly used as a kind of insulating, heat resistance and anti-chemical engineering and structural ceramic components, including ceramic electrical insulator, high voltage ceramic holder, ceramic parts in a high-temperature furnace, ceramic seal disc in pump and so on.  
Our factory produces a selection of purity of alumina from 40% to 99.8%,  all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. In order to achieve some special application for fitting, reducing the friction, increasing the insulation, we provide a serial of secondary processes after sintering, covering CNC machining, polishing, glazing, and metalizing.
We manufacture a wide range of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic discs, ceramic rods, ceramic arms, ceramic wire guides. Whatever, it's a prototyping case, or high volume demand, we believe we are able to provide you with a desirable solution.

Typical Applications

Remark:
Alumina ceramic parts are widely used in the electronic, electrical, machinery, chemistry, ceramic seal, mineral, new energy, military, aerospace, almost all modern industries.
