PB104 Bronze (CW453K)

PB104 is a high-performance wrought phosphor alloy that is suitable for more demanding applications and offers high mechanical properties.

The product benefits from various positive performance characteristics, including excellent wear resistance, superior corrosion resistance and good cold formability. Other attractive features include good spring capabilities and good resistance to shock loading. The alloy's bearing properties are exceptional and represent an excellent choice for demanding marine applications.


Typical commercial applications include:

  • Superior corrosion resistance
  • Excellent wear resistance
  • Exceptional bearing properties
  • High mechanical properties
In the commercial world

PB104 is a highly versatile bronze alloy and finds use in shafts, spindles and bearing components, high-performance gears & engine valve guides, aerospace & marine fasteners and pump components.

Improved Performance

Including Tin (Sn) in the alloying process affords PB104 numerous performance benefits. The resulting material offers exceptional spring, bearing and wearing properties while promoting good corrosion resistance. Such performance characteristics are ideal for more demanding operating environments.
