The C31400 Leaded Commercial Bronze is the combination of natural corrosion resistance with the machining ability of leaded brass. It is the combination of 89% copper and 9% zinc and also contains 2% lead that provides free-cutting characteristics. The low zinc content provides corrosion resistance in potable water with a golden colour The alloy is suitable for outdoor use owing to its resistance towards stress corrosion cracking and where the highest strength is not required.
