HI-TEMP HI-FORCE 44™ SOLDER Reviews & Ratings

BROWNELLS HI-TEMP HI-FORCE 44™ SOLDER

The Brownells Hi-Temp Hi-Force 44™ Solder is a high-strength, silver-bearing solder designed for demanding gunsmithing applications where ordinary soft solder may not provide sufficient holding power. Ideal for attaching sights, ribs, scope bases, sling swivel studs, and other firearm components, this premium solder creates durable joints capable of withstanding significant stress and vibration.

Formulated with 95% cadmium and 5% silver, Hi-Force 44™ flows smoothly and bonds quickly to carbon steel, alloy steel, and stainless steel surfaces. Its relatively low operating temperature helps minimize heat exposure to firearm components while still delivering the strength required for professional gunsmithing work.

Another key advantage is its resistance to common finishing processes. Once properly applied, the solder joint is not affected by hot caustic bluing solutions and withstands baking temperatures associated with many spray-applied firearm finishes, making it particularly useful for custom firearm builds and restoration projects.

product does not melt or flow well.

I tried to bond two metal pieces together. i used flux and a propane torch. product just doesn't melt easy or want to flow. I even tried to practice with it and had no luck.

Not for stainless

I tried to use this to install a front sight onto a stainless steel Ruger Blackhawk. I've been soldering, brazing, and welding since I was a teenager (a very long time ago). If your working on stainless, this is NOT for you.

Can anyone get this to work?

I've used Force 44 for many years. And I also use higher temp silver solders. But for the life of me, I can't get this stuff to adhere to anything, especially stainlesses. And the Copper Bond Flux is being used. Originally it was purchased to reattach a shotgun rib. This is a tedious process (for me) anyway. I thought the complications of that job were the problem. But since, I've tried a dozen times to attach sight ramps and such with it, and always remove all and start over with a solder that works for me. If anyone gets it to work, I'm missing something not in the instructions.
