FAQs About Nickel-Clad Copper Wire

Why is NCC wire preferred over pure nickel wire for Alkaline Water Electrolysis (ALK) electrodes?

While pure nickel offers excellent corrosion resistance, its electrical conductivity is relatively low. FISSOT® Nickel-Clad Copper (NCC) wire combines the high conductivity of copper (over 94% IACS) with the chemical stability of a nickel shell. In ALK environments, NCC wire significantly reduces energy consumption and heat generation while the nickel cladding acts as a physical barrier against corrosive electrolytes, making it a more cost-effective and efficient industrial electrode material.

What are the advantages of Mechanical Cladding over standard Nickel Plating?

Traditional electroplating can be porous and prone to flaking under high temperatures or bending. We utilize an advanced mechanical cladding and reduction rolling process that creates a dense, metallurgical bond between the nickel and copper at the atomic level. This ensures a highly uniform cladding thickness that will not crack or peel even during high-speed weaving or under extreme mechanical stress, greatly extending the service life in harsh environments.

What is the maximum continuous operating temperature for NCC wire?

The thermal performance of NCC wire depends on the nickel cladding ratio. NCC wire with 10% nickel content can typically withstand continuous temperatures up to 250°C. Our 27% nickel content products are specifically engineered for extreme environments, supporting long-term operation at 450°C and withstanding short-term temperature peaks up to 600°C. This makes it the ideal choice for aerospace engine wiring and industrial furnace leads.

Is the conductor solderable, and are there specific requirements for the welding process?

Yes, it is. Since the surface is a pure nickel layer, NCC wire exhibits excellent solderability. For high-temperature applications, we typically recommend high-silver content solder or the use of laser welding and spot welding techniques. Because of the tight bond between the nickel and copper core, there is no risk of base metal “bleeding” or leaching, which is a common issue with lower-quality plated wires.

Does FISSOT® offer customized nickel content and AWG specifications?

Absolutely. We understand that B2B clients have specific requirements for electrical resistance and corrosion protection. In addition to our standard 10% and 27% nickel-by-weight ratios, we can customize the cladding thickness to meet your technical benchmarks. We support production across a wide range of sizes, from heavy gauges to ultra-fine wires (such as 24 AWG and finer), catering to diverse industrial harnesses and precision sensors.
