Duralumin, a key aluminium alloy, was invented in 1909. It took seven years for Alfred Wilm, a German scientist, to create it, but it was worth the years of effort. Duralumin, with addition of copper, magnesium and manganese was as lightweight, as aluminium, but significantly exceeded it in strength, hardness and elasticity meaning it quickly became the main material used in aviation.
