PB1 (1400)

Phosphor Bronze Alloy

PB1 Phosphor Bronze

PB1 is a continuously cast copper-based alloy containing 10-12% tin. This alloy combines high mechanical strength with good ductility, corrosion resistance and wear resistance. It also offers a good resistance to shock loading but is outperformed in this area by the wrought grades. PB1 can be soldered and brazed and finds traditional use in heavy load applications run at high speeds.


BS1400 PB1 offers high wear resistance and good resistance to impact loading. With high wear resistance and excellent corrosion resistance in marine atmospheres, the alloy is used extensively in the marine industry. BS1400 PB1 offers good resistance to brine and high mechanical strength.

Typical Applications

Commercial applications for this engineering material include:

  • Worms & gears under high working loads
  • Pump & valve components
