Efficient Brazing Flux for Heavy Metals
Our white paste, based on boron compounds and fluorides, minimizes oxidation when brazing heavy metals. Achieve clean and strong joints with the optimal protection of our flux.
Brazing flux for brazing steel, copper and copper alloys, nickel and nickel alloys, and under certain conditions, stainless steels. The paste is suitable for all flame brazing processes and for induction brazing.
The paste complies with the composition and properties specified in the DVGW (German Technical and Scientific Association for Gas and Water) codes GW 2 and GW 7. It carries the DVGW certification mark (DV-0101AU2227) and the quality mark of the Quality Association for Copper Pipes.
Typical applications are found in the electrical industry, vehicle construction, and copper pipe installation.
The container should be well stirred before use. Only homogeneous paste has consistent processing properties. Adding water can change the processing properties of the paste. Flux residues are corrosive and must be removed by washing or pickling.
