C92200 Tin Bronze, also known as Navy M bronze and SAE 622, is a copper base that is alloyed with lead, zinc and tin. C922offers good corrosion resistance with good wear resistance. CDA 922 Bronze is well suited for applications that require moderate strength. 922 retains its strength at elevated temperatures. The lead in C92200 gives it good machinability. C922 Leaded Tin Bronze is available as centrifugal cast, continuous cast and sand cast. CDA922 Navy G bronze has a wide variety of uses, including bushings, bearings, gear blanks, pump bodies, valve bodies and steam fittings.
