This specification prescribes the requirements for the classification of fllr metals for brazing and braze welding. The
chemical composition, physical form, and packaging of more than 75 brazing filler metals are specified. The filler metal
groups described include aluminum, cobalt, copper, gold, magnesium, nickel, silver, and brazing fllr metals for vacuum
service. Information is provided concerning the liquidus, the solidus, the brazing temperature range, and general areas of
application recommended for each filler metal. Additional requirements are included for manufacture, sizes, lengths, and
packaging. A guide is appended to the specification as a source of information concerming the classification system
employed and the intended use of the filler metals for brazing and braze welding.
This specification makes use of both U.S. Customary Units and the International System of Units (SD). Since these are
not equivalent, each must be used independently of the other.
