High Vacuum Brazing Alumina Metallized Ceramic Sealing Ring
Description
High Hermeticity Metallized Ceramic Bushing Features: 1.Material: 96% Aluminia(AL2O3) 2.Coating Layer:Molybdenum-Mananese(Mo/Mn) 3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos. So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing . A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion. A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering. The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing. Applications: Electrical transmission and distribution Electronics industry Textile machinery Defense Medical electronics Automobile industry Sealing Solid Oxide Fuel Cells High temperature application

Metallized Ceramic Componenets: Innovacera supplies precision metallized ceramic ring in aluminum oxide ceramics for the military,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.
