It is very important to measure the hardness of the plastic, without knowing the hardness level of the material you can’t assure its quality if you want to meet the expectations of your customers then the material quality should be very high.
Diamonds are made of carbon atoms that each have 4 electrons within them. These electrons bond with the electrons of another carbon atom and so on and so forth. This results into diamonds exhibiting their characteristic hardness.
Surmise to say aluminum has almost unending uses, so it becomes important to check its hardness for the usage of various purposes. Various tests are employed for the testing hardness of aluminum. Among many two are described here-
There is a hardness scale named Rockwell scale which is used to express the hardness.
This method is used to determine the resistance of any hard material when an external force is applied.
Why test its hardness? It simply must be tested in order to conclude whether or not it is suitable for any sort of task (e.g. could it be used as a building material?). Its durability and hardiness must also be made sure of because that would determine the sort of use the metal could be put to. Let’s move on to how exactly metal hardness can be tested.
Rockwell hardness testing is the most commonly used method for assessing the hardness of specimens. Under this method, the hardness of the specimen is measured by assessing the depth of the indentation made by the indenter under the test load on the specimen surface.
