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.
