metallized ceramic parts

Custom metallized ceramic tubes are commonly made of 95% or above high purity alumina. In order to achieve the jointing from metal
to ceramics, a metallic coating will be covered on the certain surface of ceramic insulators.

The ceramic metalized tube we manufactured is famous on excellent bonding strength, super mechanical, excellent electrical
insulation, exceptional thermal features.
Jointing types:
-Alumina ceramic body + Ag plating
-Alumina ceramic body + Mo/Mn metallization
-Alumina ceramic body + Mo/Mn metallization + Ni plating
-Alumina ceramic body + Tungsten metallized + Au plating
Cosmetic quality:
- The flatness of both end sides must be less than 0,01mm
- No blister on nickel ( outer) plating at the temperature up to 1150°C
- No any crack on the surface
- No any dark spot ( impurities) on the external surface
-With evenly glaze distribution
Application:
Surge arrester, Triggered spark gaps, Thyristor housing, diode housing, Current feedthroughs, Transmission tubes, High power
receptacles, Power switches, X-ray tubes.
