Why Copper Alloys Are Architecture-Friendly. Ever since copper was discovered around 10,000 years ago, we’ve become obsessed with exploring its capacities, and all the hard work has paid off well as we now see so many alloys of copper being utilized extensively for various practical applications. Aluminium alloys are often welded with con-sumable of the same type, however, quite often over-alloyed consumables are used to compensate burn-off losses (especially with Mg and Zn because of their low boiling point) and to improve the mechanical properties of the seam.
