What is aluminium? It a silvery-white metal which is abundant in the Earth's crust. The Wright Brothers were early adopters of aluminium in engine construction. Now, aluminium is used to make cans, window frames, aircraft, fireworks and foil. Controversially, aluminium has also been used to make cricket bats. The ease of use of aluminium, and the flexibility properties especially when alloyed for strength or security for use in items such as coins, has helped make it the most widely used non-ferrous metal. Also, aluminium is often used to make kitchen utensils such as pots and pans. Finally, the sounds made by the manipulation of thin aluminium surfaces can have pleasing ASMR characteristics.
