Shaanxi Sgj International Co., Ltd.

SGJ-International was founded in China in 1949, and mainly supporting the development of China′s aerospace and nuclear industry. With China′s Reform and Opening-up, some projects have been marketized, Ceramic, Metal, Cermet, technology are some of them. We sinter ceramics and process metals and brazing in the same qualified factory, so we can strictly control the whole process and guarantee the reliability. SGJ-International have accumulated professional technology and experience with the rise of China.

Ceramics are common materials, so are the Metals. However, they have unique functions after Vacuum brazing. When we study the macroscopic celestial bodies and the microscopic particles, we often encounter the vacuum atmosphere. Ceramic Metal Seal Assemblies are the best choice to voctoring the Material & Energy & Information...

Vacuum Brazed Ceramic Metal Seal Assemblies are most commonly used in Electrostatic Particle Accelerator Tubes, Microwave Tubes, Semiconductor Feed-throughs, Laser Devices, Transmission Signals Filtering, Medical Treatment, Particle Accelerator, Space Exploration, Nuclear Industry, Aerospace Accessories, Insulation Materials, Ballistic armor...

The key to Ceramic-Metal structure depends on the vacuum Integrity and Dielectric properties, so called sealing quality. The difficulty in Vacuum Brazed Ceramic Metal Seal Assemblies is largely due to the inability of most braze alloys to "wet" directly to ceramic materials and the accumulation of residual stress once the materials have been successfully "wetted". The three contributing factors for successfully Vacuum Brazing are:

1. Material selection, 2. Joint design, 3. Wettability.
