What materials don't break?

Answer 1

Materials that are often considered to be unbreakable or highly resistant to breaking include diamond, certain ceramics, and some advanced composites like carbon fiber. Additionally, materials such as tempered glass and certain types of metals, like titanium, can have high resistance to breaking under stress. However, even these materials can fail under extreme conditions or when subjected to specific types of force. Generally, the term "unbreakable" is relative, as all materials have limits to their strength and durability.
