If brazing in air flux is required. Note, the melting range of the alloy must match the active range of the flux. The flux should be active before the alloy melts.
The Probraze Silver-flo range of cadmium free alloys represents the ultimate safety precaution against cadmium fume. Cadmium content is controlled to a maximum of 0.010 %and the use of these alloys is highly recommended for brazing components in food manufacturing equipment
