All-State®
No. 155 and 155FC Trucote®
Cadmium
Free, Low Temperature Silver Brazing Alloy Torch,
Furnace or Induction Application General
Characteristics All-State®
No. 155 is a cadmium free alloy developed primarily for application on food handling
equipment. It is lighter
in color which gives an improved appearance on stainless steel. The low melting,
good flowing and wetting properties
of this alloy minimize metal fatigue when applied to nickel and nickel base alloys.
Typical Applications
Maintenance and production joining
and repairing of steels, stainless steels, nickel and nickel base metals, copper
and copper base
alloys and high speed steels where high brazing temperatures would be harmful.
Widely used in hospitals,
laboratories, distilleries, refineries and delicate instrumentation work.
Qualities Tensile
strength —up
to 50,000 psi (35.16 kgs/mm2) Working
temperature—1150°-1200°F (621°C-649°C)
Corrosion resistance—good
AWS—A5.8, Class BAg-7
Procedures Thoroughly
clean joint area. Joint clearance should be .002" to .005". Apply All-State®
No. 110 or S-200 Flux to joint;
if necessary, thin with alcohol or water. No flux is required when using TRUCOTE®
155 (flux coated) rod. When
working on stainless steel and other materials subject to discoloration, paint
area adjacent to joint with All-State®
No. 110 or S-200 Flux. Apply heat with a slightly carburizing flame until flux
turns clear. Melt off enough alloy
to fill completely. Allow to cool slowly. Remove flux with hot water.
