Weight plays an important role in the application of electrical industry materials, which is why aluminium has been increasingly replacing copper in the manufacturing of power lines by facilitating the application of cheaper and lighter support structures. Aluminium’s greater flexibility also facilitates the application process. Aluminium’s corrosion resistance and its long-term application are unbeatable in reducing renovation expenses. For reasons of aluminium’s excellent properties, its application has also been spreading to the manufacturing of various electrical appliances.
