What Is the Origin of the Name Aluminum? Officially discovered by Hans Christian Oersted in Denmark in 1825 and used by the ancient Greeks and Romans in early civilization, aluminum is a mineral found in the earth's crust. Aluminum is most often used in kitchen utensils, building decor and construction materials.
The chief source of aluminum is bauxite ore. Aluminium is a soft, durable, lightweight, malleable metal with appearance ranging from silvery to dull grey, depending on the surface roughness. Aluminium is nonmagnetic and nonsparking. It is also insoluble in alcohol, though it can be soluble in water in certain forms. The yield strength of pure aluminum is 7-11 MPa, while aluminum alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel.
