Flux-Included Brazing Alloys for Tight Gaps

Fill in tight gaps without needing to add flux before you braze—these alloys have flux built in. When melted, these alloys form a thin liquid that easily flows into smaller gaps than standard brazing alloys. They’re often used in the piping and automotive industry. Since they don’t contain cadmium, they’re safer to use than brazing alloys with cadmium and help meet industry regulations.

Brazing Flux for Nickel and Carbide

Use this flux with silver and copper-based brazing alloys to clean and prepare surfaces. It is boron modified and residue washes off with hot water. Do not use it with titanium.

2,200° F Maximum Temperature—Flux with a 2200° F max. temperature lasts longer during brazing thanks to its low boron content, so it’s great for use on large carbide parts. It works particularly well with RBCuZn brazing alloys.
