Product Description

Custom Refractory Metallized Alumina Ceramics

We supply a variety of custom refractory metallized alumina ceramics for use in vacuum interrupters, power grid tubes, x-ray tubes and similar applications where ceramic-to-metal, ceramic to ceramic seal joints of superb bonding strength and hermeticity are required.

Our facility specializes in molybdenum/tungsten thick film metallization on 95% alumina ceramics. Also, we metallized high purity alumina, like 99% alumina, zirconia and beryllia. We utilize electro or electroless nickel/silver/gold plating as the preferred deposition over metallization. The result in a system easily brazed with cooper-silver, pure cooper, gold and other common braze alloys.

Small part-size to large part-size is availability, the min. diameter can be 1mm, the largest diameter is up to 800mm.
