C54400 tin bronze is a copper alloy with excellent properties. Below is information on its main characteristics, chemical composition, mechanical properties and areas of application:
### Properties
- **Excellent machinability**: C54400 Phosphor Bronze has excellent machinability due to its lead (Pb) content.
- **Good cold workability**: C54400 Phosphor Bronze has good cold workability.
- **Corrosion resistance**: Good corrosion resistance in atmosphere and fresh water.
- **Pressure machining only in the cold state**: due to the lead content, it is prone to thermal embrittlement during hot machining.
- **Higher strength**: C54400 has high strength.
- **Good resistance to sliding friction** : High wear reduction and good machinability.
- **Easy to weld and braze**: C54400 is easy to weld and braze.
### Chemical composition
- **Copper (Cu)**: Remainder
- **Tin(Sn)**: 3.5~4.5 per cent
- **Zinc (Zn)**: 1.5~4.5%
- **Lead(Pb)**:3.4~4.5 per cent
- **Phosphorus(P)**:0.01~0.50%
- **Fe**: ≤0.10%.
### Mechanical properties
- **Density**: 8.8g/cm³.
### Application
C54400 tin bronze is mainly used in the manufacture of parts subject to friction, such as cylinder piston chipping bushings, bearings, and bushings liner, deputy connecting rod bushings, discs and washers. In addition, it is also suitable for communication connectors, airlines, vehicles, heavy machinery and equipment, as well as industrial production of high-precision parts such as bushings, discs, coupling gaskets, such as automatic lathes, CNC machining centres commodities.C54400 tin bronze can also be used for rolling bearings, bushings, transmission gears, shafts, thrust rings and other parts.
