What is the Metal Hardness Scale?

Answer by  Snippets editor

There are many ways to test a metal's hardness — each test comes with its own corresponding scale. Three common methods are: (1) Turner-sclerometer (or just sclerometer), (2) Shore-scleroscope (or just scleroscope), and (3) the Brinell method. The tests vary in what type of object is used against the metal to be tested and how that object is applied to the metal. The sclerometer test, for example scratches a pointed diamond forwards and backwards across the metal, while the Brinell method presses a steel ball into the metal. Depending on the severity of the resulting impression, the metal is given a score based on a predetermined scale. The sclerometer scale, for example, ranges from 1 (for lead) to over 100 for hardened steel, whereas the Brinell method ranges from 6 (for lead) to over 550 (for hardened steel).

There isn't just one metal hardness scale. There are different kinds. They are used to judge the hardness of a metal which is especially important in mechanical engineering.

A metal hardness scale measures the hardness of a metal. The hardness of metals can be measured by the following methods: 1. Turner's Sclerometer, 2. Shore's Scleroscope, 3. Brinell's Test, and 4. Keep's Test.

The metal hardness scale, also known as the Moh's hardness scale, ranks minerals on a scale of 1 (soft like talc) to 10 (hard like diamonds).

This can tell you the hardness of metal or resistance of metal to plastic deformation (usually by indentation). The measurements used in metal hardness are macro, micro or nano.
