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.
