INTERNATIONAL CLASSIFICATION

AWS/ASME A 5.8 B Ag-20

FEATURES & APPLICATIONS

Low temperature joining of dissimilar metals. Excellent where tolerances and fit are not perfect.

  • Super active flux coated cadmium free silver brazing alloy with 35% silver content.
  • 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 in any alloy grade or color with small 10# (5kg) minimum orders.
  • Available bare as item #3139 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.
