Bronze PB2

 

pb2

 

Bronze PB2 is a phosphor bronze with a higher tin content than PB1, which means it has excellent resistance to wear.

 

As a result of these properties, PB2 is an ideal material for the manufacture of components such as gears and heavy sliding or reciprocating loads.

 

 

PB2 is available in bar and tube in the following sizes…

 

  • Tube from 1” OD – 16” OD
  • Bar from ½” dia – 13” dia
