About Vacuum Brazing
Vacuum Brazing is a bonding method by adding filler metal below the melting point of the both basic materials which are to be bonded at a temperature of more than 450℃; as this method makes it possible to bond diversely whether the object is a similar metal or dissimilar metal without no damage to the basic material, so the vacuum brazing is a widely used bonding method for general industry, such as automobile, aircraft, nuclear equipment, air-conditioning, refrigerator, air-conditioning & refrigerating equipment, accessories, cemented carbide tool, defense industry parts, tap & shower fittings, electrical & electronic equipment, farming machine, parts for building piping, etc.
