PB2 (1400)

Phosphor Bronze Alloy

PB2 Phosphor Bronze

PB2 benefits from excellent wear resistance with good machinability.

Wear Resistance

With increased tin content when compared to PB1, PB2 phosphor bronze alloy benefits from excellent wear resistance. The product offers high strength and good machining characteristics. Good corrosion resistance is also a feature, particularly in saltwater and brine environments. Often referred to as a ‘gear bronze’, PB2 finds typical use in applications such as pump and valve components and bearings which are subject to medium to high loads and speeds.


The alloy also offers good resistance to pounding and impact loading.

Typical Applications

Commercial applications for this engineering material include:

  • Gears
  • Bearings
  • Thrust washers
  • Pump and valve components
  • Heavy sliding applications

We stock PB2 in round bar, plate and sheet.
