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.

Full Answer. The physical properties of zinc changes some depending on the temperature it is exposed to. Normally hard and brittle, it becomes malleable between 212 and 320 degrees Fahrenheit. Once the metal hits 410 degrees it becomes brittle once more. When viewing the structure of the metal, it has a very clear hexagonal crystal structure.
