The most ductile metals are gold, silver, platinum, iron, nickel, copper, aluminium, zinc, tin and lead. Ductility means stretching or pulling a material into thin wires before it is breakable. The metals that are malleable are also ductile in nature. Hence, this property of gold has made it so much useful and costlier that it is worn as a jewellery and even used as a shielding agent for poisonous radiations. These sheets will be so thin that they become translucent which means they become semi-transparent. A gram of gold can be deformed into thin sheets whose area will be around 1 square meter. Among these, gold is said to be more malleable. Even among these metals, the malleability characteristic varies from one metal to another metal.Ī few examples of the most malleable metals are silver, aluminium, tin, platinum, zinc, iron, lead, copper, nickel and gold. Of all materials that exist on earth, the one which has got the most malleability property is metals. These are the materials that can be converted into thin sheets by hammering them or by rolling them with stress. Some materials have a characteristic of malleability that makes them change their original structure under some pressure.

Hint: Malleable is something that is easily modifiable in its structure by some external pressure.
