Continuous Cast

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