High Purity Alumina Metalized Ceramics For Electronics

We produce a broad range of alumina Metallized ceramics, mainly including purity 94.4%, purity 96% and purity 99%. The main shaping methods for the Metalized Ceramic Insulator include dry pressed, hot isostatic pressed or hot pressed which are associate with the specific configurations, applications and dimensions.

We offer a selection of types of metallization in order to reach different requirements in the different applications, the typical ones as follows:

1. Ceramic part + Molybdenum (Mo/Mn) metallization .........................2. Ceramic part + Mo/Mn metallization + Nickle(Ni) plating

3. Ceramic part + Silver(Ag) plating.......................................................4. Ceramic part + Tungsten (W) metallization + Gold(Au) plating

Sometimes, precision secondary-process is needed to achieve the fitting relationship for dimensions with tighten tolerance. The CNC machining process, precision fine grinding, lapping are carried out in-house workshop. The finest tolerance can be +/-0.001 for length, +/-0.005 for both inner and outer diameter.
