OVERVIEW

Grab-and-Go Brazing Power

When you are in the middle of a repair job, the last thing you want is to be fumbling around with a can of flux powder that’s been kicked over or contaminated with shop dust. The Aufhauser Flux Coated Bronze rod (FCB-18) solves that problem instantly. This 1/8-inch rod comes pre-coated with a high-activity flux that does the cleaning for you. You just light your torch, heat the part, and apply the rod. The flux melts right where you need it, breaking down rust and oxides so the bronze flows out smooth and fast like butter on hot toast.

This isn't just about convenience; it's about getting a quality bead every time. This "Low Fuming" bronze is designed to keep the air clearer and your puddle visible. If you have ever choked on zinc fumes from cheap brazing rods, you will appreciate the difference here. It is perfect for those tricky repairs on cast iron housings, cracked manifolds, or galvanized steel frames where you need a bond that holds tight without cracking. Because it brazes at a lower temperature than steel welding, you don't warp your parts or blow holes through thin sheet metal.

The finished weld is tough but workable. If you are building up a worn shaft or fixing a gear tooth, you can file or machine this bronze down to a perfect finish once it cools. It’s ductile, meaning it can take a bit of flexing without snapping, which is crucial for equipment that vibrates. Whether you are fixing a farm implement, plumbing a custom line, or doing artistic metalwork, keep a tube of these Aufhauser flux-coated rods in your truck. They are the ultimate multi-tool for oxy-fuel joining, saving you time and hassle on every joint.

FAQ

This rod meets the AWS A5.8 classification for RBCuZn-C, commonly known as Low Fuming Bronze.

Generally, no. The rod is pre-coated with sufficient flux for most clean metals. However, for heavily oxidized or dirty parts, applying a little extra flux to the joint area can help.

The FCB-18 internal SKU corresponds to a 3.2mm or 1/8 inch diameter rod.

Yes, this is an excellent choice for brazing cast iron because it requires less heat than fusion welding, reducing the risk of cracking the base metal.

This rod is designed for Oxy-Acetylene (Oxy-Fuel) brazing. It is not intended for TIG or MIG welding.

Yes, the bronze deposit is soft enough to be easily machined, filed, or drilled, making it great for building up worn surfaces.

It means the alloy contains small amounts of elements (like manganese or silicon) that suppress the vaporization of zinc, reducing the white smoke often associated with brass brazing.

Absolutely. Brazing burns off less of the zinc coating than electric welding, and the bronze bonds very well to galvanized surfaces.
