7 All-State®
No. 111 Lowest
Melting Silver Brazing Alloy Torch
or Induction Application General
Characteristics All-State®
No. 111 is a low melting silver brazing alloy for general use on ferrous and nonferrous
metals (excluding white
metals). The 41% silver and other elements in the alloy give it good capillary
flow, high electrical conductivity
and corrosive resistance.
Typical Applications*
Recommended for use where high brazing
temperatures may be detrimental such as in electronics, refrigeration,
air conditioning, heat exchangers and
other delicate components. All-State®
No. 111 is used where poor fit-ups are
encountered or for tight fitting joints. Qualities

good Procedures
Thoroughly clean joint area. Joint
clearance should be .002" to .005". Paint joint areas with All-State®
No. 110 or S-200
Flux reduced with water or alcohol, if necessary. Use a slightly carburizing flame,
heat broadly, keeping torch
in motion. When flux turns clear, add enough alloy to completely fill joint. Alloy
and flux may be preplaced for furnace
or induction applications. Allow to cool. Remove flux with hot water.
