Cast

The lead content in these bronze alloys is between 7 percent and 15 percent. High-leaded tin bronzes alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy C93200 is considered this family’s workhorse alloy and is widely used in many bearing applications.
