Flux Coated Brazing rod / wire is made from coating a layer of firm flux on the surface of a well formulated filler metal rod / wire. The attached flux is carefully selected to match the filler metal with high activity, non-corrosion, no moisture absorption. This perfect combination of flux and filler metal can simplify and eliminate a separate fluxing operation, thus profoundly improves the efficiency of brazing process. This conveniently self-coated rod / wire that is great for hard to reach braze joints, where it is difficult to inserting flux. It is widely used in the industries of refrigerator, air conditioning, radiator, automobile parts and tools, etc.

The flux layer is well attached on the surface of the metal rod with good ductility to prevent cracking and striping with 100% assurance. The allowance angle of bending can be larger than 30 degree. Comparing to the flux cored brazing rod / wire, attaching the flux on the surface engages good visibility of the flux vacancy. The layer is demanded to be uniform, stable, and well adhered for expiration duration of one year. The uncertainty of the diameter of this product is strictly controlled to 0.1 mm.

Gathering numerous test results from industrial research, we confirmed the ratio of flux to filler metal to design the product, making sure the continuity and efficiency.

There are three main kinds of flux coated brazing rod / wire according to different utilities, namely, silver flux coated brazing rod / wire, aluminum flux coated brazing rod / wire, and copper flux coated brazing rod / wire.
