Malleability
This article needs to be wikified. (October 2023) |
Malleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Malleable materials can be flattened into metal leaf. One well-known type of metal leaf is gold leaf. Many metals with high malleability also have high ductility. Some do not; for example lead has low ductility but high malleability.
Malleability is a physical property of matter, usually metals. The 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, aluminum, copper, silver, and lead.
Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet. The property is not seen in non-metals. Non-malleable metals may break apart when struck by a hammer. Malleable metals usually bend and twist in various shapes.
Zinc is malleable at temperatures between 100 and 200 °C but is brittle at other temperatures.[1]
How is malleability measured?
changeThere are two ways to measure it. The first is to measure the pressure or compressive stress that a material withstands before it breaks. The other test involves measuring the thickness of a metal sheet before it breaks.[2]
