Combining them creates a product that possesses the benefits of both metals: the high conductivity of copper and the low weight of aluminium.
Bimetallic wiring made from aluminium and copper-plated is being used more and more in the cable industry. The wiring has a copper coating that occupies only up to 20% of the cross-section, allowing the cable to be lighter than ones made only from copper.
The undeniable advantage of bimetallic wiring is the cost; copper prices are rising more quickly than aluminium prices, and the lower weight of the wiring due to the use of aluminium alloy reduces production costs of the cables. Moreover, wires made from aluminium and copper are safer for housing.
Together with UC RUSAL, the Aluminium Association is working on a project to expand the use of bimetallic wiring in the Russian cable industry.
Main areas of focus in the project:
