Product Description

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor

 

1. Description:

Alumina ceramic insulator(especially high alumina ceramic) for electrical industry is used for many decades as insulators or enclosures for electrical components. Additionally, it has been incorporated into many appliance, aerospace and automotive applications where moderate strength, low cost and good electrical resistance are required. This ceramic material can be formed into complex shapes prior to sintering, which has led to wide usage in a variety of applications.

 

2. Feature Advantages:

1) Abrasion resistance

2) Impact resistance

3) High hardness and high density

4) Low thermal conductivity

5) Chemical inertness

6) Good wear resistance
