Metal Hardness

In general, a metal with a high hardness characteristic will typically also have good formability, high yield strength, high electrical conductivity, or high impact strength?

Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion.
Hardness is directly proportional to yield strength, meaning both represent the same material property. By definition, a metal with high hardness has both a high tensile and yield strength.
