Leaded Bronze (also known as Leaded Tin Bronze) are well known for their unsurpassed wear performance and can be used against unhardened and not perfectly smooth shafts. The material offers reasonable resistance to brine which means it is suitable for use in pump and valve components. Along with excellent wear resistance, the alloy offers excellent machining properties and is suitable for use in the manufacture of bushes and bearings which are used under medium load as long as suitable lubrication is used. Leaded bronze also benefits from good load carrying capacity and good thermal conductivity. Common applications include connectors for wire and cable, electrical plug type connectors, door knobs, screws and nuts, bushings for corrosion, rolling mill bearings etc.
