Revainrating 5 out of 5

Brazing alloy Good Stuff

I use this for gunsmiths. I added sights and a rail to the stamped receiver. I am happy with the results. The solder is hard and I only had a few contaminants to contend with. I couldn't tell for sure if it was debris on the metal or inclusions in the filler rod.

Pros
  • Chemical composition, wt. %: phosphorus: 4.8-5.2, silver: 14.5-15.5, copper: balances. Soldering Temperature Range: 1300F-1500F (704C-816C).
Cons
  • piggy bank price
