HANDY FLO BRAZING PASTE® 500 Jewelry Pastes

HANDY FLO BRAZING PASTE® 500 is an exclusive system used by manufacturing jewelers and silversmiths for joining gold alloys. This series was developed for manufacturing jewelers and silversmiths to braze Karat gold alloys. Formulations are available to suit 3 to 22 Karat golds for a variety of color and temperature combinations.

Brazing and soldering pastes incorporate filler metal, flux, and a binder in a one-step application process. Because pastes are readily applied, they lend themselves well to both manual and automated production operations. We offer several flux/binder systems for specific temperature ranges and brazing processes.
