Lucas SilFos 5 28 Rods 5%Ag

Designed primarily for those applications where close fit-ups cannot be maintained. It has the ability to fill gaps and form fillets without adversely affecting joint strength. Slow Flow.

Sil-Fos 5 is a silver-copper-phosphorus alloy for copper-copper brazing but can also be used to join brass with an appropriate flux (e.g. Handy Flux, Ultra Flux). It is a more cost effective Ag-Cu-P alloy, though it does not penetrate deep joints easily.
