SPECIFICATION CROSS-REFERENCE CHART

Wrought

C31600, or leaded commercial bronze (nickel bearing), combines the natural corrosion resistance and machinability of C31400 with a higher tensile and yield strength resulting from the controlled addition of nickel. This alloy possesses cold workability as well as resistance to stress corrosion cracking.
