Distribution Pre-packaged Products
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. (Braze™ and Easy-Flo® Alloys), as well as low temperature, lead-bearing (Solderite™) and no-lead solders (Clean ‘n Brite™).

| Fos Flo 7 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 | ||||||||
| Sil-Fos 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 | |||||||
| Sil-Fos 2 A filler metal with comparable characteristics to Fos-Flo 7. Medium Flow. |
1190 | 645 | 1450 (1325) | 788 (718) | 2 | 91 | 7 | BCuP-6 | |||||||
| Sil-Fos 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 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 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 | ||||||||
| Solderite 50/50 Standard general purpose Tin/Lead solder for moderate joint clearances. Available as Solid, Acid or Rosin core. |

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).
