Brazing is a welding technique that uses a filler material with a lower melting point than the base material. The process involves applying a welding temperature slightly above the melting point of the filler material to melt it, wetting the surface of the materials to be joined, and then filling the joint gap. The connection is achieved through the interdiffusion of elements between the base material and the filler. Brazing has excellent potential in welding dissimilar materials with significant differences in physical and chemical properties. It is the most commonly used method for connecting ceramics and metals, offering advantages such as ease of operation, high joint strength, and suitability for extreme environments, including high temperatures and high pressures. Ceramic products used for metal connections mainly include ceramic structural components and ceramic substrates.

Applications:

Ceramic-to-metal brazing parts are widely used in industries such as power, electronic vacuum switch tubes, various types of speed control tubes, traveling wave tubes, microwave tubes, magnetrons, thyratrons, triggers, vacuum gauges, microwave night vision devices, solid fuel cells, and other related fields.
