HI-FORCE 44™ SOLDER Reviews & Ratings

BROWNELLS HI-FORCE 44™ SOLDER

The Brownells Hi-Force 44 Solder is a premium silver-bearing solder designed for firearms assembly, repair, restoration, and custom gunsmithing applications. Formulated with 4% silver and 96% tin, this non-toxic alloy delivers exceptional bond strength while operating at significantly lower temperatures than many traditional silver soldering methods. Its combination of strength, ease of use, and clean flow characteristics has made it a popular choice for attaching sights, ribs, scope bases, sling swivel studs, and other firearm components.

Hi-Force 44 flows smoothly at approximately 475°F, reducing heating time and eliminating the need for complex oxy-acetylene equipment in many applications. The lower working temperature also helps minimize discoloration, distortion, and scale formation on firearm parts. In addition, the alloy resists cracking under stress and has demonstrated excellent performance in hot bluing operations, making it an excellent choice for firearm projects that require subsequent finishing.

Requires practice

I bought the ribbon instead of the wire. In retrospect this may have been a mistake because it was difficult to determine how small of a piece I needed, place it on a warm surface, melt it by heating the metal, and spread it (tinning). I think this process would have been easier to accomplish if I had used the wire. I also discovered through trial and error that the right flux is critical, otherwise the solder will ball up and fall off. Brownell's recommends their #4 Comet flux which is a liquid. They also say you must warm each part, apply flux to them, then melt (tin) the solder onto each piece. After the parts cool you should tightly press them together and reheat the metal until the flux and solder flow, adding a thin coat of flux along the edged with a fine metal point. I found it was necessary to use an infrared thermometer to prevent overheating the solder. This required heating the parts, checking their temp, and reheating as needed, always moving the torch about or away from the parts. It does take some practice.
