This International Standard specifies the compositional ranges of a series of filler metals used for brazing. The
filler metals are divided into seven classes, related to their composition, but not necessarily to the major
element present.
In the case of composite products, such as flux-coated rods, pastes or plastics tapes, this International
Standard covers only the filler metal that forms part of such products. The melting temperatures given in the
tables are only approximate, as they necessarily vary within the compositional range of the filler metal.
Therefore, they are given only for information. Technical delivery conditions are given for brazing filler metals
and products containing brazing filler metals with other constituents such as flux and/or binders.
