C31600 Nickel Leaded
Commercial Bronze Rods

The C Nickel Leaded Commercial Bronze C31600 is the combination of 89% copper, 8% zinc, 2% lead and also contains 1% nickel. The alloy is resistant towards corrosion with higher tensile and yield strength, which is the result of the addition of nickel to the alloy. The alloy is resistant towards stress cracking and is suitably be used in high strength outdoor applications.
