Effect Of Temperature On Malleability
In most metals, increasing temperature reduces the number of grain boundaries and increases malleability. So, some metals that arent malleable under ordinary conditions respond to heat treatment. For example, zinc is brittle until its heated above 300 °F . Above this temperature, its possible to roll the metal into sheets.

Explain The Meaning Of Malleable And Ductile
Some of the more important properties peculiar to solids are malleability and ductility.
- Ductility is the property of being drawn into wire. It is a permanent strain that accompanied fracture in a tension test. It is a desirable property in machine components that are subjected to unanticipated overloads or impact loads. The ductility of the metals decreases as the temperature increases because metals become weak at increasing temperature. All ductile materials are also malleable, however, the converse is not always true.
- Malleability is defined as the ability of the material to deform to a greater extent before signs of cracks appear when it is subjected to a compressive force. The term malleability comes from the word hammer and in a narrow sense, means forged or extruded because these processes involve shaping under compressive force. In general malleability increases with an increase in temperature. Therefore, processes like forging or rolling are hot working processes where hot ingots or slabs are given shapes.

Physical Properties Can Be Extensive Or Intensive
What are Extensive Properties?
Extensive Physical Properties are those that depend on the “extent” of the system. Volume and mass are extensive, and two gallons of water at 20 deg C have twice the volume and mass as one gallon of water at 20 deg C.
What are Intensive Properties?
Intensive physical properties do not depend on the “extent” of the system. Density and temperature are intensive, when you combine 2 gallons of water the temperature stays at 20 deg and the density stays at approximately 1g/ml. Intensive properties are often constants and can be used to identify a substance.

What Does Ductile Mean In Science
: the quality or state of being ductile especially: the ability of a material to have its shape changed without losing strength or breaking When certain alloys are added to metal, hardness and strength can be improved without decreasing the ductility.
Why Are Metals Malleable
Most metals are malleable because the atoms can roll over each other and retain the structure of the crystal.
Metallic bonds involve all of the metal atoms in a piece of metal sharing all of their valence electrons with delocalized bonds.
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 sea of mobile valence electrons.
Metallic bonds consist of the attractions of the ions to the surrounding electrons. Metallic bonds are non-directional.
Whenever a metal receives a stress, the position of adjacent layers of metallic kernels shifts.
The atoms roll over each other but the environment of the kernels does not change.
The deforming force just moves the kernels from one lattice site to another.

Controlling Crystal Grains Through Temperature
Temperature has a direct effect on the behavior of atoms, and in most metals, heat results in atoms having a more regular arrangement. This reduces the number of grain boundaries, thereby making the metal softer or more malleable.
An example of temperature’s effect on metals can be seen with zinc, which is a brittle metal below 300 degrees Fahrenheit . However, when it’s heated above this temperature, zinc can become so malleable it can be rolled into sheets.
Beyond temperature, alloying is another common method of controlling grain sizes to make metals more workable. Brass, an alloy of copper and zinc, is harder than both individual metals because its grain structure is more resistant to compression stress.
What Does Malleability Mean
Malleability describes the property of a metal’s ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A malleable fabric could be planate by blow or rolling.
Malleability in metals are very important in the appliance and automotive industries. This property helps to construct refrigerators, microwaves and stoves, and also helps to construct flat and curved metal objects.
Melting Point And Boiling Point
When a metal melts or boils, this is a change of physical state.
is transferred to a substance to melt or boil it. This energy is needed to overcome the forces of attraction between the metal ions in the metal. The more energy needed, the higher the melting point or boiling point.
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds
Difference Between Malleable And Ductile
A malleable material deforms under compression, while a ductile material deforms under tensile stress. Malleable metals are beaten or pressed into thin sheets, while ductile metals are drawn into thin wires.
For the most part, malleability and ductility go hand in hand. However, there are some metals that are malleable, yet not ductile. For example, lead is malleable and can be pressed into thin sheets. Yet, it is not ductile and easily fractures when drawn into wires.

Metallic Structure And Bonding
Most of the elements in the periodic table are metals. Properties of metals can be explained in terms of metallic structure and bonding.
Some metals have properties that are not typical. For example:
- mercury has a low melting point and exists as a liquid at room temperature
- have low melting points, but also low densities, for example, sodium is less dense than water and so it floats
A substance with a high density means it has a high mass for its size. For example, the volume of liquid in a can of drink is 330 cm3. If the can was filled with sodium then the can would have a mass of around 320 g. However, if the can was filled with lead , then the can would have a mass of nearly 3.75 kg!
Malleable substances can be bent or hammered into shape without shattering, while brittle substances shatter when bent or hit.
Metals are described as ductile because they can be drawn out into thin wires.
