Detailed Product Description

EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor

 

1. Description:

Alumina (Al2 O3) is a common workhorse material in the world of technical ceramics and is utilized in an extensive variety of industries and applications. Alumina’s material properties offer electrical isolation, wear resistance, high temperature resistance, and good mechanical strength. STC’s fully dense, 99.5%, 99.8% and 99.96% alumina bodies offer improved performance over lower purity alumina ceramics in demanding operating conditions.

 

2. Feature Advantages:

1) Good advanced ceramic materials

2) High welding sealing performance

3) High hardness and high density

4) Low thermal conductivity

5) Chemical inertness

6) Satisfy various technical requests
