Large Size Metallized Alumina Ceramic Ring

Large Size Metallized Alumina Ceramic Ring

Metallized Ceramic Ring is made of high purity of alumina ceramics, a metal coating is applied on one end, or both ends to meet brazing needs. It has metallized- seal strength and hermeticity at ceramic to metal jointing application, and widely used in many different based on vacuum interrupter devices.

The main forming methods we have contain dry pressing, hot pressing, ISO pressing, ceramic injection molding and so on. We offer small part-size to very large part size. In addition, we are able to supply metallized alumina ceramic ring with different dimension precision in basis of the advanced secondary manufacturing equipment.

We provide a selection of types of metallization to meet different customers' needs, the typical metallization we offer as below:

1. Ceramic base + Molybdenum/Manganese (Mo/Mn) metallization......................................2. Ceramic base +Silver (Ag) plating

3. Ceramic Substrate + Copper (Cu) plating............................................................................4. Ceramic base + Mo/Mn metalization +Nickle (Ni) plating

5. Ceramic base + Tungsten (W) metallization +Gold (Au) plating

Prime features of Metalized Ceramics

● Excellent bonding strength to be 150MPa /mm2  ● Exceptional hermeticity and air tightness less than 1×10^-11 Pa•m3 / s

● Great electrical insulation and high volume resistivity, the electrical breakdown strength over than 18KV/mm (D•C)

● Superior corrosion resistance and free of rust   ● Good thermal shock properties and low thermal conductivity

Capability for Metalized Ceramic Parts

● Support a variety of customized complicated geometry ● Very small part size (OD1mm, H: 0.8mm) to very large part size capability

● General tolerance to high precision capability via machining● Prototyping with small quantity order to mass production capability

● Offer technical information consulation and design proposal

Applications of Metalized Ceramic Insulator

It's widely used in power grid tubes , vacuum interrupters , medical linear accelerators, power tubes, photomultipliers, x-ray tubes,

components for insulators and sensors.
