Are all metals ductile and malleable?

Answer 1

A characteristic of metals is being very malleable and ductile. However, Mercury is liquid at room temperature, and being liquid, it cannot be changed. There are probably a few exceptions to this, but most metals are malleable and ductile.

Answer 2

No, not all metals are ductile and malleable. Ductility refers to the ability of a material to deform under tensile stress, while malleability refers to the ability to deform under compressive stress. While many metals are ductile and malleable, some, like cast iron or bismuth, have low ductility and malleability.
