Description
Precision/Feedthrough insulators alumina metallized/metal
ceramics
Features:
Custom metallized ceramic tubes are commonly made of *5% 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,*1mm
- No blister on nickel ( outer) plating at the temperature up to
***0°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.
