Hardness Testing Equipment is a very important characteristic that applies to a range of materials from metals to nonmetals alike is hardness. It is defined as a material’s resistance to deformation, penetration, scratching, or other physical force. Metallography experts use equipment precisely calibrated to the appropriate hardness scales to measure hardness as per material’s requirements for different applications.
Accurate hardness testing is a simple, timely, and relatively non-destruction way of doing hardness testing making it one of the most widely used choices for engineers who are interested in materials selection, doing lot verification testing, material testing, comparing material hardness and testing across multiple objects. In addition, hardness values can typically be closely correlated with other material properties, such as tensile strength.
Hardness testing machines perform mainly three kinds of common scientific hardness tests: Brinell hardness test, Rockwell hardness test, and the Vickers hardness test. Among them, the Rockwell hardness test is most widely used, easy to carry out and more precise than other kinds of evaluations. The Brinell hardness test is typically used to evaluate materials that are too coarse or that have an exterior that is too rough for other test techniques. Based on an optical measurement system, the Vickers Hardness Test uses a diamond indenter to make a dimple that is measured and translated into a hardness value.
Our expertise in static deformation hardness has solutions for more than 1 kg and less than 1 Kg in accordance with a broad range of industry standards. These methods require the use of an indenter of known geometry and mass which is inserted into the material’s surface. To calculate appropriate hardness, the level of force applied and the depth of the groove is measured and is used to work out the appropriate hardness value for a known point on the sample. In order to find the mean hardness value for the entire sample, multiple indentations are usually done on the sample.
Our rockwell testing machine has an automatic electronic add load, computer software programming, optical measurement, and photoelectric sensor system. You can see the operating process and the results of the trial data on a large LCD display screen, you can take a print out of the experimental results. With our machines, you can do hardness test of cast iron, non-ferrous alloys and metals, different kinds of annealing, and materials coatings. It is useful even for soft metals, like pure aluminum, lead, and tin.
