Bronze brazing flux is a chemical compound that is used to prevent oxidation and promote the flow of molten brazing filler metal during the brazing process. It is typically applied to the joint to be brazed in the form of a paste, powder, or liquid.
Bronze brazing flux is composed of a variety of chemicals, including borax, zinc chloride, and fluorides. These chemicals react with the oxides on the surface of the metal to form a protective layer that prevents further oxidation. They also help to lower the surface tension of the molten brazing filler metal, which allows it to flow more easily into the joint.
Bronze brazing flux is used to braze a variety of metals, including bronze, brass, copper, steel, and cast iron. It is also used to braze heat-resistant alloys such as nickel silver and Monel.
To use bronze brazing flux, the joint to be brazed should be clean and free of dirt, grease, and oil. The flux should then be applied to the joint in a thin, even layer. The brazing filler metal can then be applied to the joint and melted. The flux will help to prevent the filler metal from oxidizing and will also help it to flow more easily into the joint.
After the brazing process is complete, the excess flux should be removed from the joint. This can be done by scrubbing the joint with a wire brush or by using a solvent.
Bronze brazing flux is a safe and effective way to prevent oxidation and promote the flow of molten brazing filler metal during the brazing process. It is a necessary tool for any brazing operation.
