Introduction:
NC025 CuNi19 is a type of copper-nickel alloy that contains approximately 19% Nickel, along with other elements such as iron and manganese.
This alloy is known for its excellent corrosion resistance, particularly in marine environments where it is exposed to seawater and salt spray.
CuNi alloys like NC025 CuNi19 are commonly used in applications where resistance to corrosion and biofouling is crucial, such as in marine engineering, shipbuilding, offshore oil and gas platforms, and desalination plants. The alloy's resistance to corrosion in seawater is due to the formation of a protective oxide layer on its surface, which helps prevent further degradation.
