SPECIFICATION CROSS-REFERENCE CHART

The lead content in these alloys is between 7 percent and 30 percent. High-leaded tin bronzes are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. The high-leaded tin bronzes are ideal for bearing applications where there could be a loss of the lubrication boundary. These alloys perform excellent in unforgiving environments where foreign matter may be present, such as dirt and other foreign materials. The high-leaded alloys are able to envelope foreign matter due to their malleable nature and, in doing so, protect the wear surface of a mating part such as a shaft.
