Brazing - The American Welding Society (AWS) defines brazing as a group of joining processes that produce coalescence of materials by heating them to the brazing temperature and by using a filler metal (solder) having a liquidus above 840°F (450°C), and below the solidus of the base metals. For a more in-depth explanation, see How Brazing Works.

Soldering - Soldering has the same definition as brazing except for the fact that the filler metal pastes used has a liquidus below 840°F (450°C) and below the solidus of the base metals.

Welding - In welding, fusion takes place with melting of both the base metal and usually a filler metal.

Here at McCombs we sell only the highest quality silver brazing, soldering and fluxes. Brazing alloyies sold here are manufactured in the USA by Harris and Lucas Milhaupt. The Harris Products Group is a world leader in metal working products used in the brazing, soldering, welding, cutting and gas distribution industries.

Lucas Milhaupt carries pre-packaged brazing filler metals, fluxes, and solders, including SIL-FOS®, developed and patented by Handy & Harman in 1931, the original copper/phosphorous brazing alloy used by thousands of manufacturers and contractors.


  • Soldering two metals together can be tricky. Using the correct solder for the job is important. To help make the correct choice, please see our user guide and watch this video.
