Choosing conductive metals for different industries and applications can be a challenge. Copper is often used in cables and wires because of its excellent conductivity and malleability. But it is relatively heavy and expensive compared to aluminium. Switching to aluminium, which is lighter and significantly less costly than copper, is a viable option in many cases. Using aluminium successfully is a matter of understanding the capabilities of this conductive metal and how to deal with the challenges it presents.
The greater availability of raw aluminium compared to copper accounts for this significant difference in price. After oxygen and silicon, aluminium is the third most common element in the Earth’s upper crust, while copper is ranked 25th in availability on the list of raw materials. Assessment of current prices is further reinforced by the volatility of the raw materials market.
If aluminium is used as a conductor material, its lower conductivity requires a wire size that is approximately one-third larger than that of a copper wire. In the end however, the insulating material used with the wire plays a crucial role in performance and an aluminium wire can possess the same current carrying capacity as a H07RN-F copper wire. Aluminium’s larger wire size would only be a disadvantage in applications requiring tight spacing, such as when installed in densely packed control boxes.
The facts for aluminium speak for themselves when it comes to the issue of weight. As a raw material, aluminium is approximately 70 percent lighter in weight than copper. This can be helpful in the efforts of numerous application fields looking to reduce the weight of all components. Naturally, when used in electrical cables, the lower weight makes them easier to install. High-voltage lines have long been made from aluminium; the lighter weight reduces the tensile force placed on wire and masts significantly. But even industries such as automotive manufacturing and the aeronautical industry are switching to aluminium wires.
