High Bonding Strength Metalized Ceramic Insulator for High Currency
Feedthru
Many technologies have been used to join ceramics to metals, or
ceramics to ceramics. Brazing is a desirable method for joining process because of its capability for
joining dissimilar materials, high reliability and precision production tolerance.
To join ceramics to itself or to metal, the critical problem is the
poor wettability of ceramics by filler alloys. When a metal layer
applied on a certain surface of ceramic parts, it will help to fix
the poor wettability well. That's why metalized ceramics play a
very important role between ceramics to ceramics, ceramics to
metals joining technology.
We manufacturer a variety of ceramic metalization components with
different materials, different designs, different specifications.
Many amazing solutions were to be supplied to our customers to
reach their toughest technical challenges.

Typical application of metalized ceramic components
Metallized ceramic insulators are widely used in electronics,
high-vacuum technology, sensors, and medical fields, like vacuum
interrupters, electron tubes, feedthroughs, medical linear
accelerators/ power tubes, photomultipliers, X-ray tubes, and
pressure sensors.
