👉 A term that can be defined as "ultralight" or "ultra-light," which means it is very thin and does not weigh any more than a tiny fraction of its original mass, but still has enough mass to cause significant deformation. This property allows materials to be used in applications where high density is important, such as aerospace engineering, medical implants, and energy storage. For example, ultraplasticity refers to the ability of materials to deform or change shape under extreme forces without
