Malleability is a physical property because it can be observed without a change in composition of a substance. Chemical properties are those which are observed during a chemical reaction, for example the tendency of iron to rust and form iron oxide, a new substance.

Malleability is a physical property because it can be observed without a change in composition of a substance. Chemical properties are those which are observed during a chemical reaction, for example the tendency of iron to rust and form iron oxide, a new substance.
Malleability is a typical property of metals. It's the ability to be shaped or flattened by compressive stress, such as hammering or rolling. In metallic bonding the valence electrons are free to move around. This allows atoms to change position under stress without fracturing the material. This shifting of position of atoms relative to other atoms doesn't produce a different substance.
A roll of aluminum foil is an example of the malleability of metals. Gold is the most malleable metals, with the ability to be flattened into extremely thin sheets.
