Packaging Standard 1.5; 20 kg Applications BrazeTec h 280 is a dosable flux paste which can be applied via a suitable applicator at the mouth of the gap. Normally it is used in mechanised brazing procedures. The paste should be homogenised prior to loading in the tank of the applicator. The flux paste is suitable for brazing any steels, copper and copper alloys as well as nickel and nickel alloys. BrazeTec h 280 can be used for all flame and particular for induction brazing procedures. During brazing the organic binder must burn out completely. Typical applications are found e.g. in the automotive and electrical industry.
