What Is Malleability in Metal? - ThoughtCo
24/11/2019· Therefore, the more grain boundaries a metal has, the harder, more brittle, and less malleable it will be. Malleability vs. Ductility While malleability is the property of a metal that allows it to deform under compression, ductility is the property of a metal that allows it to stretch without damage.
