Copper Nickel Alloy Wire CuNi1 NC003 OEM Low Resistance in Heating Applications
CuNi1 is a copper-nickel alloy composed of approximately 90% copper and 10% nickel, offering excellent resistance to corrosion, especially in marine environments and seawater. The alloy is known for its strength, durability, and good formability. CuNi1 is highly resistant to pitting and crevice corrosion, making it ideal for applications exposed to harsh conditions like saltwater or industrial environments. Additionally, CuNi1 has good thermal and electrical conductivity, although slightly lower than pure copper.
It is commonly used in marine applications, such as in shipbuilding for pipes, heat exchangers, and seawater-resistant components, as well as in chemical processing and desalination plants. Its combination of strength, corrosion resistance, and weldability makes it a versatile material for demanding industrial applications.
