Product Description
High Vacuum-tight Ceramic-to-metal
Product Features
Metallized ceramics is to firmly adhere a layer of metal film on the surface of the ceramic to realize the combination between the ceramic and the metal, so that it has both the characteristics of ceramics and the properties of metal. There are various ceramic metallization processes such as molybdenum-manganese sintering method, gold electroplating, copper electroplating, tin electroplating, nickel electroplating, vacuum plating and so on.
Application field
Metalized ceramic products are widely used in power, electrical appliances, communications, national defense, aerospace and many other aspects, as well as lightning protection and other overcurrent and overvoltage protection devices.
