Silver Braze 54
AWS: BAg-13
Silver Braze 54 is employed in numerous furnace brazing situation because of its low zinc content. The US Air Force specifies it for many jet engineer subassemblies. It is used for making joints that are subjected to elevated temperatures, ranging up to 700°F (370°C) particularly on stainless steel.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
Characteristics
Silver Braze 54 is an intermediate temperature silver brazing alloy with a rather long, 235°F (130°C) melting range. It has a tendency to liquate (Separation into low and high melting constituents) if heated slowly through its melting range. Therefore, it is preferable to use this alloy where the assembly can be heated rapidly to brazing temperature. The long melting range of this alloy is useful when wide gap joints are hand fed since semi-fluid alloys can be working across the gaps. Flux is recommended.
Properties
Stainless steel butt joints furnace brazed (in atmosphere) with Silver Braze 54 develop room temperature tensile strengths of 50,000 – 60,000 PSI with commercial joint clearances. Optimum joint clearances will produce higher tensile values. The results listed below were generated from brazed butt joints which were tested under standard room temperature conditions. Tensile Strength (lbs/in2) Copper: 30,000 - 35,000 Brass: 35,000 - 50,000 Nickel-Silver: 35,000 - 40,000 Elongation (%, 2" gage length) Copper: 10-19 Brass: 13-25 Nickel-Silver: 2-3
