The use of silver alloys for joining metals has shown a large increase in recent years, and this development has taken place in spite of the great improvements that have been made in welding and brazing processes in which base metals or their alloys are used. These alloys have been called silver solders and classed as hard solders to diflerentiate them from the common lead tin alloys which are used extensively. It is believed, however, that “silver brazing alloys” is a more descriptive term to use and indicates more definitely the temperatures at which they melt and the type of joint made with them.

The following definition is suggested:

Silver Alloy Brazing—A method of joining metals by means of heat, wherein the filler metal is a silver alloy with a melting point above 1000 degrees F., but lower than those of the metals or alloys to be joined.
