Copper nickel 90/10 flanges are piping grade that connect different piping equipment to provide stability and strength to different components. The 90/10 copper nickel flanges are produced with a 90% copper and 10% nickel content with small additions of iron and manganese. This content gives them higher strength and gives them enhanced corrosion resistance properties. The 90/10 Copper Nickel flanges help in connecting pipes of different configurations and work well in seawater systems.
