Distribution Pre-packaged Filler Metals & Fluxes

Lucas Milhaupt carries pre-packaged brazing filler metals, fluxes, and solders, including SIL-FOS®. SIL-FOS®, the original copper/phosphorous brazing alloy, was developed and patented by Handy & Harman in 1931.

Distribution Pre-packaged Products

Available either in bulk or pre-packaged lots are filler metals for brazing copper-based alloys (SIL-FOS®), steels, stainless, etc. (SILVALOY® and EASY-FLO® Alloys), as well as low temperature, lead-bearing (SOLDERITE™) and no-lead solders (SILVABRITE®).

HANDY FLO® (formally SIL-FOS® 6M)

Recommended for use where a close fit-up cannot be maintained. Has the ability to fill gaps and form fillets without affecting joint strength. Slow Flow.

SIL-FOS® 15

(Formally SILVALOY® 15) Best alloy for general copper-copper brazing in the SIL-FOS® family. For copper-to-copper joints the phosphorus in the SIL-FOS® product serves as the fluxing agent and no separate flux is necessary. For brass applications however, flux is recommended. For use where close fit-ups cannot be maintained SIL-FOS® 15 works well to bridge gaps. Highest joint ductility of the entire SIL-FOS® family to best withstand the stresses inherent in refrigeration. Slow Flow.

SIL-FOS® 2

(Formally SILVALOY® 2) A filler metal with comparable characteristics to FOS-FLO® . Medium Flow.

SIL-FOS® 5

(Formally SILVALOY® 5) 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.


1190 645 1495 (1325) 815 (720) 5 89 6       BCuP-3
SIL-FOS® 6

(Formally SILVALOY® 6F) A very fluid filler metal for close fit-up work. Low melting range makes it ideal where temperature is a factor. Fast Flow.

SIL-FOS® 6i

(Formally SILVALOY® 6) A fluid filler metal that offers intermediate flow characteristics. An acceptable alternative to SIL-FOS® 15 where vibration and thermal cycling stresses are not severe.

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 metals 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).
