When metals are heated of cooled, either contracts or expands. This is one of the properties of metals.
Fusibility
Fusibility is a mechanical property of metals to be liquefied by heating.
Density
Density is a physical and mechanical properties of metals which is defined as mass per unit volume.
Toughness
Toughness (Mechanical Property of metal) is the ability of the metal not to break in pressures applied such as tearing, shearing, stretching, bending or deformity.
Elasticity
Elasticity is a Physical and Mechanical Property of metals to be able to return to its original shape after it has been deformed.
Ductility
Ductility is a physical and mechanical property of metals that allows the metal to be deformed, drawn, bent or twisted into different shapes without fracture or breaking.
Malleability
Malleability is a physical and mechanical property of metals, which is the material’s ability to deform under stress without breaking or cracking.
Brittleness
Brittleness, a mechanical property of metals, is the property of a metals to bend or deform without breaking or shattering the metal.
Hardness
The mechanical properties of metals which is Hardness is the resistance to deformation, penetration, abrasion, cutting or distortion.
Electric Conductor
Because of the free electrons that are present in the metals, it becomes a good electrical conductor. This is why this is one of the Properties of metals:
