malleability,

property of a metal describing the ease with which it can be hammered, forged, pressed, or rolled into thin sheets. 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 120°C;. to 150°C;. Impurities adversely affect the malleability of metals.

Malleability

 

the capacity of metals and alloys of undergoing forging and other types of pressure shaping (rolling, drawing, pressing, or stamping). Malleability is a property of most pure metals and of steel, brass, and Duralumin, as well as some other copper, aluminum, magnesium, and nickel alloys. It is characterized by plasticity—that is, the ability of the metal to undergo deformation under pressure without destruction—and by its resistance to deformation. Malleable metals combine relatively high plasticity with low resistance to deformation.

malleability

The property of a metal that permits mechanical deformation by extrusion, forging, rolling, etc., without fracturing.
