Description

2.1030 (CuSn8) 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. It shows the following features and properties:


  • Exceptional bearing properties
  • Excellent wear resistance, fatigue strength and frictional properties
  • Excellent tensile and fatigue strength
  • High ductility
  • High corrosion resistance
  • Related Standards
