Product Description

 

The Ceramic Surfaces for Brazing, the surface must be metallized.
Compare to Glass seal, Ceramic seal has exceptional resistance to thermal and mechanical shock as well as corrosion. While it requires more complex manufacturing processes and sophisticated engineering, the price is obviously higher.

Advantages of Ceramic-to-Metal Seals
* More solid, durable hermetic seal and better electrical insulation
* Used for more harsh conditions, such as high and low (cryogenic) temperature, corrosive, high pressure, and high vacuum environments
* High mechanical strength, less fracture when applied to high vibration and high g-load conditions
* Shows strong bond and an excellent seal with metals and alloys, such as copper and Cu alloys (CuNi) and to nickel and Ni alloys.

 

 

Features

1) High-intensity sealing, high air-tightness, high reliability, good heat resistance
2) Excellent insulation performance and high temperature resistance
3) Good mechanical , electrical and thermal conductivity
4) Great bonding strength
5) Widely used for all electric products and electric heating products
