Nickel Copper wire is progressively being used for manufacturing cables for high temperature applications. They work wonder when applied in applications with high chemical demands. This kind of wire comprises copper wire with concentric nickel plating cover. These wires have amazing mechanical properties and have high corrosion resistance property. More and more users are using Nickel Copper wires in HF applications for reducing high frequency loss. These wires come with diameters, ranging from 0.030mm to 0.500mm. Their applications can be seen in Litz wires too.
Features, Composition, and Uses of Nickel Copper Wire
Important properties of these nickel coated copper wires include 250 to 300 N/mm² tensile strength, 150 to 250 N/mm² yield strength at 1 per cent elongation, 94 per cent resistance (IACS), 55 S*m/mm², and good solderability.
Cupronickel is an alloy, where you will find 75 per cent copper, 25 per cent nickel, and insignificant amount of manganese. You will find this alloy in silver-colored modern circulation coins. However, composition of the metals changes in cupronickel as per its use. However, nickel copper alloy found in resistors and thermocouples come with 45 per cent nickel and 55 per cent copper. In fact, you will be surprised to know that Monel metals are also nickel-copper alloys, where the least amount of nickel used is at least 63 per cent.
Cupronickel are used for manufacturing condensers, heat exchangers, and piping in seawater systems because this alloy’s high resistance to corrosion, created by seawater. In fact, for this feature this alloy is being used for manufacturing hulls, crankshafts, and propellers of fishing boats, tugboats, and other kinds of working boats. Many people are also using Nickel Copper wire as wiring materials because they are capable of sustaining even in the extreme weather conditions at certain temperatures.
Technical Discussions on Nickel Copper Wires
It has been estimated that more than 10,000 tons of copper wires are coated with either silver r nickel every year. Whether it is professional electronics industrial sectors, telecommunication, computer, defense, airframe, or aerospace, cupronickel wires are used for stranded conductors in high performance electric cables. These wires are also being used spark ignition leads and fuses as well as high temperature cables. One of the reasons of this wide range use is that these nickel plate copper wires are capable of resisting temperature up to 750 °C. Besides corrosion property of these kinds of wires, they are known for their easy wielding features. However, nickel plated coppers are can’t be soldered easily. In fact, the nickel-copper wire manufacturers have to plate nickel under carefully controlled conditions so that a pore-free as well as suitably ductile deposit for drawing can be manufactured. In the industrial front too use of this kind of alloy is increase because of their inherent properties. Though its use started in aerospace and aviation industries, currently they are also use in different industrial applications too including those in pyro metallurgical plants, petrochemical plants, glass, aluminum, steel, and iron industries.
