Description TAURUS Bronze Brazing Rod (BBR) is a widely used brazing and bronze welding rod depositing metal which has good tensile strength. This versatile brazing rod is ideally suited for sheet metal work such as vehicle bodies, tubular and galvanised iron fabrication as well as for copper and for brazing cast iron, and heavy steel sections. The flux coated bronze brazing rod doesn’t require any extra flux. The bare bronze brazing rod will required M15 flux.
