Aluminium usage in aeronautics goes back as far as the aeronautical industry itself. Indeed, the Wright brother's struggle to find an engine with the specifications they required, namely a weight of 90Kg and a power output of 8hp, lead them to develop their own engine using a cast aluminium block. The use of this material and their ingenuity surpassed even their own expectations, creating an engine which weighed 77Kg and offered 12hp. Its low mass, high strength and sheer breadth of alloys suitable to meet the physical requirements of air travel make it absolutely essential to almost all aircraft's construction.
