Welcome to NewTech Materials & Analytical, Ltd NewTech is an innovative company engaged in service of hydrogen brazing, manufacturing & development of gas sensors based upon innovation of materials and technologies. NewTech's hydrogen brazing: Hydrogen is one of the most active agents for reducing the oxides of many metals during brazing. If an oxidized metal is heated to a sufficiently high temperature in dry hydrogen, the oxide of that metal will be reduced to native metal and the oxygen emissions will combine with hydrogen to form water. Since the ideal situation in brazing is to create a joint with the native metal, a dry hydrogen environment can greatly assist in ensuring a successful braze. The finished product is more aesthetically pleasing, offering a well-defined, uniform braze fillet. Parts are bonded across the entire mating surface, thus optimizing strength and thermal conductivity. Parts are metallurgically bonded, offering strong hermetic seals to 10-10 cc/s vacuum scale. Parts come out of the furnaces ultra-clean; free of surface hydrocarbon contaminants, oxide layers and chemical cleaning residues. Industrial applications of hydrogen brazing: Semiconductor industry - Medical industry - Traveling Wave Tube (TWT) - Electron Beam Devices - Sealing of Solid Oxide Fuel Cells High vacuum applications
- Vacuum tubes
- Other hermetical seal-required devices.
