The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of

Most of them are very soft, with a hardness under 150 HB. The popular materials in this group are Aluminum and Copper-based alloys. Machinability rates are very high compared with ferrous materials and are typically in the range of 200-400%. Because of this, a component made from these materials has low production costs.

For example, though they respectively hold ratings of three and four on the Mohs scale, the minerals calcite and fluorite have a difference in hardness that measures approximately 25 percent, while diamond—with the highest rating of ten—is approximately 300-percent harder than corundum, which has a rating of nine.

It's actually used to measure the amount of energy the material can absorb at the limited state. 6) Shear strength: the maximum shear load a material can withstand before failing divided by its cross-sectional area. Generally, Steel, Titanium, Tungsten and Inconel are considered the strongest four metals.

The Mohs hardness test is one of the earliest attempts at defining and comparing the hardness of mineral materials. The Mohs scale consists of values from 1 

Mohs hardness test uses 10 reference materials of varying hardness as the scale for the test. The softest material used is talc (value=1) and the hardest material is diamond (value=10). Given that the references used for the Mohs scale do not have a graded increase, the Mohs scale lacks accuracy and is only a rough me See more
