Product Description

High Brazing Strength Metallized Ceramic Tubes for Feedthru

Depositing a metallic coating of Molybdenum-manganese(Mo-Mn) / Tungsten (W) based paints followed by nickel /gold plating, Afterwards, an interface offered that enables ceramic to metal or ceramic to ceramic joining by means of brazing via solder.

In common case, a layer of metallization layer is applied with a typical thickness of 10 to 30 µm after cured. The metallization sintering process is carefully controlled to achieve a balanced mixture of Molybdenum particles surrounded by a matrix of glass to ensure high bond strength between the metallized layer and the ceramic base. In order to increase the wettability at subsequent brazing processing, we make the nickel plating to be 2~6 um. We can offer a selection of metallization types as below:

1. Ceramic body base + Mo/Mn metallization.......................2. Ceramic body base + Ag plating.......................3. Ceramic body base + Sn plating

4. Ceramic body base + Mo/Mn metallization + Nickle plating.............................................5. Ceramic body base + W metallization + Gold plating


We are capable of offering high precision metallized Ceramic Bushing via fine grinding, CNC machining, cutting processes. The tolerance can be +/-0.01 for overall dimensions.
