Malleable metals. Malleability is a physical property of matter, usually metals. This property usually applies to the family groups 1 to 12 on the Modern Periodic Table of Elements. It is the ability of a solid to bend or be hammered into other shapes without breaking. Examples of malleable metals are gold, iron, copper (to a degree) and lead. Malleability is the ability of a metal to be hammered into thin sheets. Gold and silver are highly malleable.
Iron requires considerably more effort to pound into a sheet and is therefore less malleable. Yet, both are metals. In contrast, non-metallic elements, such as carbon or sulfur, shatter into pieces when hammered. Malleability is a valuable property because it allows metals to be shaped into useful forms.Pure gold is the most malleable metal. Silver, aluminum, lead, tin, and copper are also very malleable. Heating usually increases malleability.For instance, zinc, at standard temperatures is brittle, but becomes malleable at temperatures between 248Â°F (120Â°C) and 302Â°F (150Â°C).ron requires considerably more effort to pound into a sheet and is therefore less malleable.
