Last week’s post, we shared the composition and material density of copper, aluminium and aluminium alloy. That determines the strength and conductivity of each material. The chart above shows the comparison between copper and three different grades of aluminium. The unique properties of each grade of material makes it suitable for different uses. For instance:…

Copper, aluminium and aluminium alloys are common materials. For electrical conductors, the copper has to be 99.9% pure and the aluminium must be at least 99.5% pure. Alloys have slightly lower purity as other composite metals are added for tensile strength. Aluminium are more commonly used for aerial and overheads due to it being lighter…
