Most jewelery brazing and soldering applications are covered under our Jewelers' Flux selection. However, the jewelery industry is constantly changing and developing new metals for creative applications. Okai manufactures a wide range of fluxes that are typically used for industrial applications, but may have use in cutting-edge jewelery manufacturing as well. Feel free to browse our expanded list of brazing and soldering fluxes and contact us with any questions you may have.

STANDARD BRAZING FLUXES

Name	Description	Filler Metals	Temperature
