This metal hardness chart organizes different types of metal using the Mohs hardness scale, a metric used by scientists to determine the scratch resistance of different minerals. With diamond at the top of the scale at a score of 10, elements and alloys can fall along the metal hardness scale from 10 (the most scratch-resistant) to 1 (the softest).

The Mohs scale of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. The scale was introduced in 1812 by the German geologist and mineralogist Friedrich Mohs, in his book "Versuch einer Elementar-Methode zur naturhistori

The Mohs scale is a chart of the relative hardness of the various minerals from softest to hardest. The scale was developed in 1822 by Frederich Mohs. Since hardness depends upon the crystallographic direction, there can be variations in hardness depending upon the direction in which one measures this property.

Mohs Hardness Scale, a system founded by Friedrich Mohs in 1812, is a type of chart used to test and contrast the hardness of different minerals. The scale, which can best be described as ordinal rather than linear or logarithmic, provides a rough measure of a mineral’s hardness based on its smooth surface resistance to scratching and abrasion.

Mohs Scale Hardness. Developed by the German geologist Friedrich Mohs it is currently the most commonly used scale of hardness. It is based on whether a mineral can scratch another mineral, if it can it means it has a higher hardness. A table of the minerals that Mohs used to define a hardness number, along with the absolute hardness of

The back of each chart shows Hardness numbers and their corresponding Crystals. The Reference Chart lets you locate, at a glance, what a Crystal’s hardness is, based on the Mohs scale, a method used to measure how hard a substance is when it is scratched by another substance; in other words, a mineral’s relative resistance to scratching

Mohs hardness scale was developed by German geologist, Friedrich Mohs, in the 1800s and is used worldwide to quantify the hardness of a mineral. The scale is not exact but is based on the ability of one substance (whose hardness is known) to scratch and damage another. For example, if a newly discovered mineral is scratched and damaged by

On average, it is 6.5. If you check granite hardness on the Mohs scale, you will find it harder than marble and softer than quartzite. Following are some of the hard granite stone ratings: Granite Mohs hardness - (6-7) Quartzite Mohs hardness - (7) Marble Mohs hardness - (3-4) Sandstone Mohs hardness - (6-7) Slate Mohs hardness - (2.5-4)

The Mohs Scale of hardness also referred to as the Mohs Scale of Mineral Hardness was devised in 1812 by Dr Frederich Mohs who was a Germany mineralogy specialist. He took 10 minerals that were fairly commonly known and ranked them in order of hardness from 1-10.

Mohs Scale of Mineral Hardness In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary. Hardness Mineral Associations and Uses 1 Talc Talcum powder.

Our chart is based on the Janka Hardness Scale which is the industry standard for gauging the ability of various wood species to resist denting and tolerate normal wear. It also indicates the effort required to either nail or saw the particular wood species. The woods are listed from hardest to softest, so the higher the number, the harder the

Friedrich Mohs developed the Mohs' hardness scale in 1822. This scale indicates the relative hardness of the different minerals start, softness - 1 to hardness - 10.

The Mohs Hardness Scale is a set of ten reference minerals (numbered 1 through 10) that are used to determine the relative hardness of minerals and other objects. In this test the hardness of a mineral is defined as its "resistance to being scratched". A list of the Mohs Hardness Scale Minerals is shown in the table below.

Friedrich Mohs developed the Mohs' hardness scale in 1822. This scale indicates the relative hardness of the different minerals start, softness - 1 to hardness – 10.

Secondary standards may be used if they are first standardized against the primary standards. Mohs recommended the use of "a fine and very hard file" that has a hardness of about 6 1/4. Other useful substances are: window glass 5 1/4, pocket knife 5+, copper coin 3, and finger nail 2+. Minerals of hardness 1 have a greasy feel.
