Companion Fluxes

Kapp Lunar Flux™ in an 8 oz. tub has been designed specifically for soldering casted Aluminum, Diecast, Zamak, White Metal and Pot Metal using Alumite™ solder. Residue is electrically conductive and slightly corrosive. Learn More

Kapp Golden Flux™ PASTE has been designed specifically for soldering Aluminum to Aluminum and Copper. Kapp Golden Flux™ PASTE stays where you put it. It is designed for use on Aluminum-to-Aluminum or Aluminum-to-Copper sheets and tabs where fluxing action is over a limited area. Conversely, it does not flow as well into tight joints as the liquid Golden Flux™ formulation. Both Kapp Golden Flux™ formulas provide a low resistance contact surface. Learn More

LIQUID Kapp Golden Flux™ has been designed specifically for soldering Aluminum to Aluminum and Copper wire pigtail splices, and for Aluminum to Copper, Brass or plated terminals and hot dip coating of Aluminum cable connectors. LIQUID Kapp Golden Flux™ is designed to flow well and draw the solder into tight butt and lap joints. Conversely, it is designed to flow, so use Kapp Golden Flux™ PASTE on sheets, tabs and connections where fluxing action is over a limited area. Both Kapp Golden Flux™ formulas provide a low resistance contact surface. Learn More

Flux designed specifically to work with KappZapp3.5™ and KappZapp4™ Silver solders to remove the oxide layer on Copper to allow a strong metallic bond between the solder and the base metal. Its active range is 350°F - 500°F (176°C - 260°C). Learn More
