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 substra…
