Can aluminium float in water

A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.

Aluminum pellets will not float in water. Aluminum's density is 2.7 g/cm3. Water's density is 1.0 g/cm3. Since aluminum has a higher density (it is heavier) it will sink in water.

*** However, if the pellets are very small, the surface tension of the water will hold them, causing them to "float." :)

Put aluminum film in the water and see it for yourself.

Yes, it will float as long as it has a big surface. It will not if it is a small piece.

Aluminum powder floats on water due to the surface tension of the water. However if you break that surface tension by adding detergent or soap to the water the aluminum powder sinks.

Does Aluminium react with water?

Eventually, it will. But Aluminium has a great propensity to form a protective film of oxide, and this film is essentially inert. So aluminum may be used for boating or float planes, for example quite safely.


How do you separate aluminium from iron without a magnet?

One way would be to find a liquid that is chemically inert to both metals and has a density between that of iron and that of aluminium. In such a liquid, the aluminium would float and the iron would sink.
