Silvaloy 404 is a special purpose, intermediate temperature silver brazing filler metal formulated principally for the brazing of carbides. It also is an effective alloy for the brazing of stainless steels. Silvaloy 404 is a very sluggish, intermediate temperature brazing filler metal with a long (360°F/200°C) melting range. It has a strong tendency to liquate (i.e. separate into low and high melting constituents). This property is used to advantage in applying this alloy to the brazing of carbide tips. Available forms: Wire, strip, engineered preforms, specialty preforms, powder and paste. Information provided by Lucas-Milhaupt. |
