    Copper cables allow superior power transfer than aluminium. Besides the different local & ideal material properties of copper versus aluminium, the grain size of the different materials, corrosion aspects & so forth, need to be evaluated.

    Typically, when aluminium cables begin to create major resistance after a few years, they will be replaced with copper. You may save some upfront cost by using aluminium cables, but, it will get you later.

    The Copper Development Association will be sure to have further details on this.
