BRONZE BASED ALLOYS
C93200
CAST C93200
The lead content in high leaded tin bronze alloys is between 7.00% and 15.00%. These alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy C93200, also termed C932, bearing bronze, SAE 660, SAE 660 bronze, and SAE 660 bearing bronze, is considered this family’s workhorse alloy and is widely used in many bearing applications.
