96% Al2O3 Alumina Metallized Ceramic Ring for Power Grid Tubes RF Windows

Metallized Ceramic Ring Componenets:

FUBOON supplies precision metallized ceramic ring in aluminum oxide ceramics for the medical, and aerospace industries. Through spray, needle, and brush coatings or screen printing our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.In order to achieve the welding between ceramic and metal, the ceramic surface firmly adheres to a layer of the metal film, which is ceramic metallization.Refractory-metalized aluminum oxide ceramics widely use in power grid tubes, vacuum interrupters, and similar applications where metal to ceramic joints of exceptional strength and hermeticity is required.
