Reliable Bronze is proud to offer you a lead-free continuous cast bronze bar known as FEDERALLOY® NO LEAD C89835. It is an equivalent to standard CDA 932 or SAE 660. A component known as Bismuth has replaced lead in this bar, thus eliminating any environmental concerns associated with the machining or fabricating processes.

Federalloy® NO LEAD C89835 is as strong as CDA 932. Federalloy® NO LEAD C89835 wears the same as CDA 932. Federalloy® NO LEAD C89835 is just as easy to machine as CDA 932 but without the brittleness found in other Bismuth substitutes.
