These layers can be delaminated into thin sheets, meaning they can be processed into flat films, which are also extraordinarily strong in comparison with their thinness.

WebMalleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Malleable materials can be flattened into metal leaf. One well-known type of metal leaf is gold leaf. Many metals with high malleability also have high ductility. earths forbidden secrets by maxwell igan
