What is Silicon Aluminum Bronze?

It is well known that the Aluminum Bronze families of alloys offer distinct advantages in a number of areas.  These attributes include higher mechanical properties, excellent anti corrosive abilities, along with good fatigue and anti-galling strengths.  For the most part these advantages were obtained with the tradeoff of a lower machinability rating.

This lower machinability rating can be overcome with the addition of silicon to the alloy composition.  The end product is what we refer to as Silicon Aluminum Bronze.  As a result of the addition of Silicon this new alloy combines the higher mechanical properties of the aluminum bronzes with a high machinability rating generally only found in alloys with lower mechanical properties.
