| NOTE:
The Sil-Fos and Fos-Flo filler
metals are for use with copper and copper alloy base metals.
Do not use these materials to join ferrous materials as brittle
phosphide compounds will be formed at the interface. The Sil-Fos
and Fos Flo filler metails have a unique characteristic called
the "Flow Point" (listed in parentheses). The "Flow
Point" is defined as the temperature at which the filler
metal is fluid enough to capillary through a joint even though
not completely liquid (i.e. above the liquidus temperature).
