Product Description

High Purity Alumina Ceramic Metallized Housing

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 3~10um. We can offer a selection of metallization types as below:

1. Raw ceramic + Mo/Mn metallization 2. Raw ceramic + Ag plating 3. Raw ceramic + Sn plating 4. Raw ceramic + W metallization + Au plating

5. Raw ceramic + Mo/Mn metallization + Ni platingMetallized Ceramic Cylinder
