Conversion table/chart for Brinnel and Rockwell hardness scales and tensile strengths. Rockwell Hardness (HRC and HRB) and Brinell Hardness (HB or BHN) are most commonly used for steel and iron castings. A metal’s hardness is basically a measure of how much it resists bending, so you can see how that is an important factor in making wire jewelry. gem ID checklist tutorial. The mohs hardness or mohs scale is used to measure the resistance that a smooth surface has towards scratching or abrasion. Contingent upon where a water test is performed this data will be accounted for in mg/L (milligrams per Liter) or GPG (grains per gallon). ASTM E 140 - 97, September 1999, Conversion for Non-Austenitic Steels, Table 1. Vickers hardness is a measure of the hardness of a material, calculated from the size of an impression produced under load by a pyramid-shaped diamond indenter. These values are approximate and for guidance only. ]. They have They have excellent electrical and thermal conductivities, exhibit good strength and formability, have outstanding resistance to The hardness value is near the limit (within 15%) of the acceptable range of the particular hardness scale. Copper and copper alloys are widely used in a variety of products that enable and enhance our everyday lives.
