Aluminum is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon. Aluminum is a soft, durable, lightweight, malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminum is non toxic, non magnetic, and non sparking. It is also insoluble in alcohol, though it can be soluble in water in certain forms.
