PB102 (CW451K)

Phosphor Bronze Alloy

PB102 Phosphor Bronze

PB102 is the most common grade of wrought phosphor bronze used in the UK due to its ability to be used across an extensive range of general-purpose applications.

Due to its tin content, PB102 offers superb spring qualities as well as high corrosion resistance that are close to that of aluminium bronzes in a range of atmospheric conditions. It combines good mechanical properties with excellent cold-forming properties and has a fair machinability rating.


PB102 has superior cold-forming properties and good spring properties. With low magnetic permeability and high wear resistance, the alloy has improved corrosion resistance. PB102 is an extremely versatile alloy which can be used across a wide range of general engineering applications.
