PB1 Bronze

Phosphor bronze is an alloy of tin and copper to which phosphorus has been added during the casting process. It is a single phase alloy suitable for cold working.

The benefits of PB1 include its good resistance to corrosion, (approaching that of aluminum bronzes) and excellent mechanical and high fatigue strength.

PB1 is a tough material of very wide application. Typical examples of its use include the following…

 

·      Heavily loaded bearings

·      Re-drawing

·      Weaving

·      Cold heating

·      Spinning

 

 

PB1 is mainly available in hollows and rods… 

Hollows from 1”OD – 16”OD                       Rods from ½”dia – 13”dia
