Type “U” is a finely ground, all-purpose paste flux for brazing with silver alloys. It readily dissolves unwanted oxides and inhibits further oxidation. Type “U” provides the clean surface needed for the ready flow of molten silver alloys.

The Gasflux Company recognizes that each brazing application is unique. We would welcome the opportunity to discuss your application and recommend the right paste flux that best meets your needs.
