Leaded Tin Bronzes

Product Detail

Leaded Tin Bronzes: Alloy Nos. C92200, C92300, C92700

  Some tin bronzes contain small amounts of lead. In this group of alloys, lead's main function is to improve machinability. It is not present in sufficient concentration to change the alloys' bearing properties appreciably A few of the leaded bronzes also contain zinc, which strengthens the alloys at a lower cost than tin. The leaded bronzes in this family otherwise have similar properties and application as the tin bronzes.
