SGJ Vacuum Joining/ Welding/ Soldering/ Weld/ Seal/ Sealing Ceramic to Metal Vacuum Brazing Service

Vacuum Brazing is a joining process, like Ceramic Metal Seal Assemblies whereby a filler metal or brazing alloy is heated Specified melting point and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting temperature while protecting with a suitable atmosphere, usually a flux. There are a range of available vacuum brazing alloys. Such as: Kovar Alloy, OFHC Copper, Stainless Steel SUS 304L...
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 of 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. We Shaanxi Sgj International Co.,Ltd. have our own unique solutions to ensure the stability and reliability of our products....
