Lucas-Milhaupt Silvaloy® 255 Brazing Alloy
Categories:	Metal; Nonferrous Metal; Copper Alloy; Precious Metal; Silver Alloy; Solder/Braze Alloy
Material Notes:	Formerly Silvaloy® A25T. Silvaloy A25T is an economical filler metal for ferrous and nonferrous joints not requiring high ductility or impact strength. It is similar to Silvaloy A40T, however flow is less active and temperature range and brazing temperature are greater. This alloy is not ductile during cooling. After brazing, it must be allowed to cool without being subjected to mechanical or thermal stress. Information provided by Lucas-Milhaupt Warwick, LLC (formerly Wolverine Joining Technologies).
