PB104, sold by Columbia Metals as COLBRONZE, is a wrought phosphor bronze which provides exceptional bearing properties in severe operating conditions. Its high tin content (8%) and addition of phosphorus ensure superior wear, fatigue and corrosion resistance to ordinary phosphor bronzes and gun metal. PB104 is an alloy of choice for demanding marine and corrosive environments.
