Soldering Salts and Babbitt Flux
Soldering salts or Babbitt flux are used for roll-tinning, babbitting and solder pot covering, as well as for general purpose soldering and tinning. In addition to our soldering salts, we also offer a liquid soldering flux for No. 72 that is particularly effective in for babbitting operations.

All soldering salts are RoHS compliant.
Superior Solder Salt is formulated as a Babbitting or cover flux. These solder salts have a wide process window due to their low melt point and high temperature capabilities and are recommended for copper, copper-based alloys, and ferrous metals. Solder salts are effective for dissolving oxides and tarnish, especially when molten.
Superior No. 27 and Tara 350 solder salts are formulated for processes incorporating tin-lead alloys with tin contents ranging from 30-85%. They can also be used with lead-free alloys. Tara 350 solder salt becomes active at a lower temperature than No. 27.
Our No. 72 is a liquid soldering flux based on Zinc Chloride, as well as other activators. This flux is idea of babbitting operations, promotion strong wetting of the babbitt alloy to the bearing surface. Flux residues are water-soluble and should be washed off after soldering. Available in gallon bottles, pails and drums.
