Nickel Copper Alloy for Electrical Wires? – Is it Good or Bad

Copper is extensively used for the manufacture of electrical wired because of its high electrical conductivity and low resistance. Copper wires are also popular because of the tensile strength and the ductility of the metal. Copper is relatively cost effective and the price points largely depend on the quality of material used.

Copper wires are standardized and accreditation need to be checked well before sourcing it. Ideally, they should be procured from established and reputed manufacturers who are quality conscious and known for providing high quality wires for safety and reliability. Alongside copper wires, variations in the form of alloys are also available. One of them is cupranickel which is a nickel copper alloy.

How is Nickel Copper Alloy Different?

When nickel is added to copper, it brings along some of its own properties and creates a new set of properties for the alloy. Some of the distinctive features of this allow include:

1. More tensile Strength: When nickel is added to copper, the tensile strength of the metal changes and is enhanced. Nickel increases the tensile strength and therefore, in terms of manufacturing ease, the nickel copper alloy is a better choice as compared to pure copper, for drawing wires.
2. Higher Proof Strength: Wires made from a mix of copper and nickel has more proof strength as compared to those manufactured by copper alone. Therefore wires manufactured from nickel copper alloys are likely to be more strong and durable and hence would last longer. So, if you wish to opt for wires that are likely to last longer, then the alloy made ones will be better suited for sure.

3. Better Corrosion Resistance: Wired manufactured from nickel copper alloys will be better suited for environments that are exposed to extensive corrosion. For instance if the wires are meant for humid conditions or marine usage, it is always more advisable to stick to cupranickel instead of copper alone. Better corrosion resistance means less frequent replacements required and saving on capital costs.

4. Lower Electrical Conductivity: Although the alloy appears to be a superior choice to copper in many ways, it does not match up to the electrical conductivity of copper. So, if you are looking for highly effective wires, copper is perhaps still the best choice as compared to nickel copper alloy.

Choice Depends on Nature of Usage

Choice of wires depends on the nature of usage. If you are looking for high speed performance, copper is perhaps better. However, if longevity is your preference, the alloy could suit your purpose better.

Once you have determined on your choice of make, it is important to understand that the advantages can only be realized when you have sourced your wires from a trusted source. Make sure you choose from a company that sticks to standardizations. It is also important to know whether the company you are sourcing from sticks to the right norms for manufacturing and adheres to all directives.

Visiting the manufacturing facility and checking out the proceedings there will ensure complete peace of mind, especially if it happens to be a bulk purchase.
