Product Information

CuSn11Pb2 (CC482K, formerly Rg3) is a leaded tin bronze alloy with 11% tin (Sn) and 2% lead (Pb), offering high strength, excellent wear resistance, and superior corrosion resistance, particularly in marine and industrial environments. The tin content provides mechanical strength and hardness, while the lead content enhances machinability and self-lubricating properties, making it ideal for heavy-load, high-friction applications. Typical applications of CuSn11Pb2 (CC482K) include:

  • Bearings and bushings: Used in heavy-duty machinery, hydraulic systems, and construction equipment, ensuring low friction and wear resistance.
  • Gears and worm wheels: Suitable for power transmission components, offering excellent load-bearing capacity.
  • Pump and valve components: Common in marine, chemical, and water treatment industries, thanks to its superior corrosion resistance.
  • Sliding elements and wear plates: Ideal for guide rails, thrust washers, and friction-intensive applications, ensuring long service life.
  • Shipbuilding and offshore equipment: Resistant to seawater corrosion, making it suitable for propellers, shafts, and marine hardware.
  • Steam and hydraulic fittings: Used in pressurised systems requiring high mechanical strength and thermal resistance.
