Hardness is the property of a metal / alloy to resist the physical effects like plastic deformation, penetration, indentation and scratching.
- Hardness is a measure of the resistance of a material to plastic deformation induced by either indentation or abrasion.
- Some materials (like metals) are harder than others (like plastics, wood, etc) due to this property.
