PB2 Bronze

This 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, this bronze is an ideal material for the manufacture of components such as gears and heavy sliding or reciprocating loads.

 

This bronze is available in bar and tube in the following sizes…

 

PB1 is mainly available in hollows and rods… 

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