Leaded Bronze Bush

leaded bronze (also known as leaded tin bronze) is readily available and less expensive when compared to other bearings alloys. Our range includes SAE660, which is one of the most popular alloys of this type. Smiths also offer our own designated material, SigmaBronze7 which offers an added advantage of being available in metric sizes. Leaded bronze alloys 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.
