This is a property of solid metals. Capable of being shaped or formed, by hammering or pressure.

The property of solid metals that make them capable of being shaped or formed by hammering or pressure is malleability. All solid metals are malleable. This means they can be pressed, hammered, or rolled into a different form without them breaking. Malleability is measured by how much compressive stress a metal takes before it breaks. The crystal structure of a solid metal determines its malleability.
