The concept of unmalleability has fascinated philosophers and scientists for centuries. The definition of unmalleability can vary from person to person, but in general, it refers to an object or phenomenon that is incapable of being changed into a different form.

Malleability has been studied from a variety of perspectives, including physics, chemistry, and engineering. For example, steel is malleable because it can be beaten into various shapes, but it is also strong and resistant to breaking.

Some objects are inherently malleable, while others may become malleable after being exposed to a certain force or heat.
