Ductility : It is the property of a material which enables it to be drawn into a wire form. The percentage elongation and contraction of area, as determined from a tensile test are a good practical measure of ductility.
The most ductile metal is Gold.
Brittleness : It is a property of material by virtue of which it breaks without undergoing any deformation on application of stress. A brittle material does not have a plastic region and can only deform slightly before it fractures. An example of a highly brittle material is glass.
Malleability : It is a property which is similar to ductility. The ability of a material to be beaten or rolled into plane sheet is called malleability.
Gold is the most malleable metal while nickel is the least malleable.
Elasticity : It is the measure of a material’s ability to return to the original dimensions following deformation by a load. An example of an elastic material is a rubber band.
Plasticity : If none of the strain in a stressed material disappears upon removal of the stress the material is said to be plastic.
Hardness : It is the measure of a material’s resistance to deformation of its surface due to impact, erosion or wear.
Strength : The greater the load which can be carried the stronger the metal.
Toughness : A material’s ability to sustain variable load conditions is a measure of the materials toughness or tenacity. It is the ability of a material to oppose rupture. A tough material does not break easily. Materials could be strong and yet brittle but a material which is tough has also strength and resilience.
