SW-MSF2--Multi Sol Liquid Flux™ - Flux for Dissimilar Metal Soldering

Multi Sol Liquid Flux™ has been designed specifically for the low temperature soldering of Aluminum to Aluminum, Copper, and most dissimilar metals including Pot Metal. This flux is golden colored, chloride-free, and organic based.


  • Contains 56-60% active ingredients consisting of amines and complex inorganic fluorides.
  • Effective fluxing action occurs at 350-550°F (177-288°C). Be aware the flux will char or burn at temperatures above 550°F (288°C).
  • Applications include: Aluminum to Aluminum or Aluminum to Copper wire pigtail splices, Aluminum to Copper, Aluminum to Brass or plated terminals, Hot dip coating of Aluminum cable connectors to provide a low resistance contact surface, Where it is desirab
  • Recommended soldering alloys: Multi-Sol ™ - Tin-Zinc-Cadmium Solder Rods
  • NOTE: Residue is electrically conductive and slightly corrosive. We recommend that user remove any residue with hot water or alcohol and a clean rag.
  • The information in the specifications tab below represents the physical properties of Multi Sol Flux™. Many factors, such as materials, temperature, and method of application determine the most effective flux. We recommend testing appropriate fluxes
