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.

Flux Removers


Aerosol Can	Pen

For applications such as printed circuit boards, switches, and heat sinks, these removers get rid of any residue left behind by no-clean flux.

Pen—Pens are best for spot cleaning and precise removal.

For Removing—Lead-free and rosin flux removers are designed to remove the flux residue but not impact the remaining solder. It's common to use this remover when soldering with lead-free and tin/lead solders.

Cannot Be Sold To—Flux removers cannot be sold to the listed jurisdictions/areas due to import and product regulations.
