Overview

OEM Alumina Ceramic Ring  alumina ceramic grinding drilling machining parts


As structural ceramic products have the advantages of high insulation strength, high temperature resistance, corrosion resistance, abrasion resistance, good vibration resistance, high mechanical strength, etc., they are able to show high stability and excellent mechanical properties even in very harsh environments or engineering application conditions.Mainly used in petroleum, chemical medical equipment, low temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery and other fields.

Aluminium oxide ceramic ring has many advantages.Firstly, it has excellent insulating properties, which can effectively isolate the current and protect the safe operation of electronic equipment and systems.Secondly, it has high hardness and abrasion resistance, which can withstand forces such as high-speed movement, friction and pressure for a long time.In addition, the high temperature resistance of alumina ceramic insulating sheet makes it suitable for applications in high temperature environments.For example, it can serve as insulation and protection in power transmission and electrical equipment.In addition, since alumina ceramic insulating sheet has a low dielectric constant, it can reduce current loss and signal interference, and improve the transmission efficiency and stability of the system.

Product Description

1060X656-5

Customised Alumina Ceramic Rings


High temperature resistance

Withstand up to 1600℃.

High hardness

Vickers hardness is higher than 1500HV0.5, its hardness is only second to diamond.

Good wear resistance

Its wear resistance is equivalent to 266 times of manganese steel, which can extend the service life of the equipment.

Light weight

The density is only half of steel, which can greatly reduce the load of equipment.

Reliable quality

16 years precision ceramic processing experience, ISO quality management system certification, quality assurance, zero risk commitment!


The process of isostatic pressing is used to produce high-precision alumina ceramic shafts and sleeves and high-precision silicon carbide shafts and sleeves. The isostatic pressing and moulding of the blanks are subjected to uniform force, small deformation, and can meet the high requirements of parallelism and perpendicularity.
