Metal hardness is a characteristic that determines the surface wear and abrasive resistance. The ability of a material to resist denting from impact is related to hardness as well as a material's ductility. Various degrees of hardness may be achieved in many metals by tempering, a heat treatment process used in cold rolled and cold worked metals.

There are three primary procedures for determining a material's hardness: scratch hardness testing, the Leeb rebound hardness test, and indentation hardness testing. Scratch hardness testing The Mohs scale of hardness can be used to determine the hardness of a material by comparing it to a list of standard materials with known hardness.

So, without further ado, here is the countdown of ten hardest materials on Earth, from weakest to strongest. #10. Spider Silk Spider silk possesses a rare balance of strength and durability. It owes that quality to the thousands of small strands that comprise it, courtesy of the spiders' diligence.

There are six main hardness tests that can be carried out: Vickers, Rockwell, Brinell, Mohs, Shore and Knoop. Which one to apply depends on the type of material 

Unlike other well-defined material properties, there is no standard scale for measuring hardness. Materials are tested using various methods,

Material hardness is the ability of a material to withstand force without deformation, scratching, penetration, and indentation.

Baecol hardness, brinell hardness, hardnees, indenter, Mohs hardness, Rockwell hardness, shore hardness, strength, vickers hardness Material hardness and hardness testing Material hardness is the property of the material which enables it to resist plastic deformation, usually by penetration or by indentation.

The most common Brinell, Rockwell, and Vickers hardnesses of metal materials are all indentation hardness. The hardness value indicates the ability of the 

5 Toughness It is the property of a material which enables it to withstand shock or impact. Toughness is the opposite condition of brittleness. The toughness is may be considering the combination of strength and plasticity. Manganese steel, wrought iron, mild steel etc are examples of toughness materials. #6 Brittleness

Hardness of a material correlates to its elastic modulus and its tensile strength, although the relationship is not always direct and depends on the test involved. Hardness of metals is usually done using an indenter, with a "hardness number" being related to the depth of the indentation. Ceramics and other very hard

In materials science, hardness is the ability to withstand surface indentation ( localized plastic deformation) and scratching. Hardness is probably the most poorly defined material property because it may indicate resistance to scratching, resistance to abrasion, resistance to indentation or even resistance to shaping or localized plastic

The screwdrivers are made of steel iron because it is very hard, and the rods used in building houses concrete are made of iron, not copper because the hardness of iron is more than that of copper.
