Metals vary in this respect; pure gold is the most malleable. Silver, copper, aluminum, lead, tin, zinc, and iron are also very malleable. Some heating usually increases malleability.Zinc, for example, at ordinary temperatures is very brittle, but is malleable in the temperature range from about 120Â°C. to 150Â°C. Impurities adversely affect the malleability of metals.The Columbia Electronic Encyclopedia, 6th ed.

Some heating usually increases malleability.
This is different from ionic bonding (where no electrons are shared at all) and covalent bonding (where the bonds exist only between two atoms). A metal that you can hammer into thin sheets is malleable. Gold, silver, aluminum, iron, and copper are malleable. Non-malleable metals such as tin will break apart when struck by a hammer. A metal behaves as an array of metal ions or kernels immersed in a âseaâ of mobile valence electrons. Metallic bonds consist of the attractions of the ions to the surrounding electrons.
