It says that demand for aluminium cable, especially in the power industry, is already rising and “certain to increase in the coming years” – at the expense of copper.
“There will be substitution, and it will have an impact on the market,” said Christophe Allain, the company’s corporate purchasing director for non ferrous metals, addressing the Cesco copper conference in Chile earlier this year.
“We have customers who in the past thought the cost differential between the two metals would not be sustainable [and so stuck with copper]. But now
they ask directly for an aluminium cable design.”
This is not Nexans necessarily talking its book – the company manufactures both copper and aluminium cable.
One area where substitution is likely to increasingly occur is in car wiring. Industrial copper cabling could be switched to aluminium in the railway, aeronautics and wind farm sectors. But the biggest threat to copper is in the power sector.

Nexans, the large French wire and cable maker, announced on 7th February that its full year operating revenues, at constant non-ferrous metals prices, increased by 6% to EUR4.87B (USD6.60B). However, the company noted that acquisitions were responsible for the increased revenues and organic sales growth was roughly flat compared to 2011. Nexans reported mixed revenue growth by sector, with the group's Industrial Cables unit and the Distributors and Transformers unit showing organic sales growth, whilst the Nexans reported contraction in its Power Transmission and Utilities and Operators businesses. In the Industrial Cables unit, high double-digit growth was noted in the demand automotive wiring harnesses, with the company highlighting its strong position with German autos companies as a decisive factor. The company also noted strong growth in supplying cables to the oil industry and the aeronautical industry. Weak European growth was noted in Nexan's Automation and Capital goods business, as well as in the railways sector, with Nexans noting that they expect railway investment to pick up in China in H2 2013.

Copper ranks second to silver as an electrical conductor. The copper cladding of LEONI Histral® H16 ensures a good electrical conductivity whenever mechanical properties do not play a primary role.

High-frequency (HF) technology In HF technology the so-called „skin effect“ ensures that the current flow is restricted to a very thin layer situated on the surface of the conductor and that the overall resistance in the conductor is reduced. LEONI Histral® H16 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized. Aeronautics and automotive technology Weight is of major importance for the construction of airplanes and automobiles. LEONI Histral® H16 is particularly suited for larger cross-sections here that can be employed for the transmission of power, where there is a significant weight reduction potential. Shielding braids LEONI Histral® H16 features a resistivity lending itself well to shielding braids because high coverage can be achieved at a comparatively low weight. The fact that aluminum suffers from the drawback of having a poor contact resistance is largely offset by the copper cladding. Heating applications The combination of a relatively good resistance value with a rather low mechanical resilience suggest that LEONI Histral® H16 may well be used in all kinds of heating applications that are not exposed to a permanently varying level of stress.
