Ceramic Metal Seal Assemblies Sgj Vacuum Components in battery and cell BNC Coaxial Electric Feedthrough Electrode/ Insert/ Conductor
SGJ BNC electrical feedthroughs are consist of two concentric conductor paths which are separated and insulated with 96% alumina ceramic. These are single-ended grounded shield feedthroughs.
Kovar Alloy 4J33: Kovar is a Nickel-Iron-Cobalt, controlled expansion alloy. It's expansion characteristics match alumina ceramics. This alone ensures it is a highly popular controlled expansion alloys for hermetic sealing applications (Mainly used in Ceramic Metal Seal Assemblies)
OFHC Copper TU1: CTU1/C102 is an oxygen-free copper which has better forming, resistance to hydrogen embrittlement, and brazing characteristics than C110 ETP. CTU1/C102 has good solderability and corrosion resistance and is used for high current applications.
Stainless Steel SUS 304L: SUS 304L Stainless Steel famous for its resistivity, fall under the category of Stainless Steel Tubes. Threaded, Hot Rolled, Cold Rolled, Heat Exchangers, Annealed, Pickled.... All these products belonging to the SUS 304L Tubes catalog serve as the prime building blocks of electrochemical, shipping, construction and gas industries.
Metallized Alumina Ceramic: Vacuum brazing of ceramic and metal requires metal coating in the welding area of ceramic. It ensures good air tightness of metal and alumina metallized ceramic brazing joint in vacuum environment. We SGJ have our own unique patented solder formula to ensure the stability and reliability of our products... The key of Ceramic-Metal structure based on the vacuum tightness, so called sealing. And , Metallized ceramic bonding area Via vacuum brazing technology is the only solution
