SAE 660 Bronze or C93200 as it also commonly known is a high leaded tin/ bearing Bronze.
SAE 660 is one of the most widely used alloys on the Bronze range, mainly due to its versatility as a medium range Bronze that make it suitable for many applications.
This Bronze has good hardness and strength qualities as well as good wear resistance, it also has excellent machining properties and antifriction qualities.
SAE 660 will not be subject to dezincification and provides a reasonable amount of resistance to sea water and brine that make is suitable for pump and valve components but not as must as PB1 Phosphor Bronze.
It is also suitable for application such as bearings as well as bushings that are under medium loads and speed while using adequate lubrication.
