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.
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®).

|Product||Solidus||Liquidus||Nominal Composition, %||AWS & International Standards||Technical Documents*||MSDS Safety Documents*|
|50/50 (SOLDERITE™ 50/50)
Standard general purpose Tin/Lead solder for moderate joint clearances. Available as Solid, Acid or Rosin core.
|AL 802 - Flux cored HANDY ONE®
Solder for joining aluminum and aluminum alloy. Alloy is cored with a non-corrosive flux.
|AL 822 - Flux cored HANDY ONE®
High strength, low temperature braze for joining aluminum to aluminum and aluminum to copper. Easy to use, contains a non-corrosive flux.
(Formally SILVALOY® 45) Versatile alloy, used for most ferrous and non-ferrous metals. Contains Cadmium, therfore exercise extreme caution as Cadmium fumes are toxic.
(Formally FOS-FLO® 7 / SILVALOY® 0) An economical, very fluid medium temperature filler metal for use with copper, brass and bronze. Withstands moderate vibration. Fast Flow.
|1310||710||1460 (1350)||793 (730)||92.8||7.2||BCuP-2|
|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.
|1190||645||1460 (1300)||795 (705)||6||88||6|
(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.
|1190||643||1475 (1300)||802 (705)||15||80||5||BCuP-5|
(Formally SILVALOY® 2) A filler metal with comparable characteristics to FOS-FLO® . Medium Flow.
|1190||645||1450 (1325)||788 (718)||2||91||7||BCuP-6|
(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|
(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.
|1190||645||1325 (1275)||720 (690)||6||86.8||7.2||BCuP-4|
(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.
|1190||643||1425 (1300)||775 (705)||6||87.5||6.5|
|SILVABRITE® (CLEAN 'N BRITE™)
Lead-free, silver-bearing high-strength solder used for applications requiring close joint clearnces.
|SILVABRITE® (CLEAN 'N BRITE™) -- No Lead
Silver-bearing solder with good strength used in potable water system applications requiring no lead.
|SILVABRITE® 6 (CLEAN 'N BRITE™ 6)
Lead-free, silver-bearing high-strength solder used for applications requiring large joint clearances. Easiest Silver-bearing soft solder to work with as temperature sange permits bridging loose fit-ups if necessary.
|SILVABRITE® 95/5 (CLEAN 'N BRITE™ 95/5)
General purpose Tim/Antimony solder.
(Formally BRAZE™ 380 / SILVALOY® A38T) Economical general purpose brazing alloy for joining both ferrous and nonferrous base metals. Free flowing.
(Formally BRAZE™ 401 / SILVALOY® A40) A more economical filler metal with a fairly narrow melt range, this alloy has application for both steel and copper-based applications.
(Formally BRAZE™ 450 / SILVALOY® A45) General purpose filler metal for joining ferrous, non-ferrous and dissimiliar metals with large joint clearances.
(Formally BRAZE™ 452 / SILVALOY® A45T) Low temperature, general-purpose alloy with better flow properties than SILVALOY® 450.
(Formally BRAZE™ 505 / SILVALOY® A50N) Best general purpose filler metal available. Recommended for stainless steel as it retards interface corrosion. Nickel content provides superior adhesion to base metal surfaces.
(Formally BRAZE™ 560 / SILVALOY® A56T) Lowest temperature, Cadmium-free filler metal, very fluid alloy flow.

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).
