The metal that can float on water: Radical new material could lead to 'indestructible' warships and ultralight cars


Researchers have demonstrated a new type of metal so light it can float on water.

The radical new material, called a metal matrix composite, was developed with the US Army.

A boat made of such lightweight composites will not sink despite damage to its structure.

The radical new material, called a metal matrix composite, was developed with the US Army and could be used in everything from warship to cars.

The new material also promises to improve automotive fuel economy because it combines light weight with heat resistance.

Although syntactic foams have been around for many years, this is the first development of a lightweight metal matrix syntactic foam.
