The main difference between ductility and malleability is that ductility refers to a material’s ability to stretch under tension, while malleability refers to its ability to be deformed by compression.
Ductility is measured by elongation at fracture, while malleability is measured by reduction in cross-sectional area.
Both properties are important in materials engineering and are applied in different areas of manufacturing.
What is ductility?
Ductility is the ability of a material to deform plastically without breaking when subjected to tensile stresses. In other words, it is the material’s ability to stretch and change its shape in a single direction.
The degree of ductility of a material is measured by the amount of deformation it experiences before breaking, which is called fracture elongation.
Ductility is commonly applied in the manufacture of wires, cables and tubes, where a material is needed that can be stretched without breaking. Examples of ductile materials include copper wire, aluminum sheet, and steel.
What is malleability?
Malleability is the ability of a material to be plastically deformed without breaking when subjected to compressive stresses. In other words, it is the ability of the material to change its shape in all directions, regardless of the direction of the applied force.
The degree of malleability is measured by the amount of deformation a material experiences before breaking, called reduction in cross-sectional area.
Malleability is commonly applied in sheet and sheet manufacturing, where a material that can be molded into complex shapes is needed. Examples of malleable materials include lead foil, gold leaf, and aluminum.

In summary, ductility and malleability are two important properties in materials engineering that refer to the ability of a material to change shape without breaking.
Ductility refers to a material’s ability to stretch under tension, while malleability refers to its ability to be deformed by compression.
Although both terms are related, they have different applications and are measured differently.
Understanding these differences is crucial to selecting the right material for a specific project and ensuring its success.
