What are Copper Nickel Flanges C70600?

As the biggest manufacturer for flanges in China,Haihao Group offers certified Copper Nickel flanges,Cu-Ni 90/10 weld neck flanges, SO flanges,blind flanges and threaded flanges.

Copper nickel alloys that have moderate strength and thermal stability in high temperature level,offers excellent corrosion resistance,especially in marine salt water environments.

Copper nickel alloys have good fabricability and high inherent resistance to biofouling.The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance. Copper nickel alloys are of two types that include 90/10 and 70/30. The 90/10 alloys are widely used as they are inexpensive. The 90/10 copper nickel alloys have great resistance to sea water corrosion due to the presence of significant amounts of manganese and iron
