FEATURES & APPLICATIONS

For color matching stainless steel and for low temperature high strength joints in the food, medical and pharmaceutical industries.

  • Super active flux coated cadmium free silver brazing alloy with 56% silver content.
  • Rare flux coated silver available in 3/64″ (1.2mm) diameter for precision work.
  • Special “Fast Flow” flux coating provides twice the base metal cleansing action of conventional silver flux coatings.
  • No odors from rubberized compounds yet the flux coating is totally flexible and non-fragile.
  • The only flux coated silver flux strong enough to clean oxidized stainless steel.
  • Available bare as 3159 for use with 5130 flux.

Brazing Instructions

Welding Techniques: After cleaning metal, preheat generally to 350°F (200°C) then heat the joint area to 800°F (420°C). Melt off some flux and allow it to flow throughout the joint. Then add alloy.
