Product Description
Copper-nickel alloy wire is a type of wire made from a combination of copper and nickel. This alloy is known for its excellent corrosion resistance, high electrical conductivity, and good thermal conductivity. It is commonly used in applications such as electrical wiring, heating elements, and various electronic components. The specific composition of the alloy can vary depending on the desired properties and application requirements.
Copper-nickel 44 refers to a specific alloy that contains approximately 44% nickel and the remaining percentage is copper. This alloy is commonly used in various applications, including electrical connectors, marine hardware, and coinage. It offers excellent corrosion resistance, high electrical conductivity, and good thermal conductivity.
DIN spools are available for the package as per your requests.
Stranded or bunch wires are available.
Enameled wire can be tailor-made.
