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.
