In production of materials in industries and different hard objects, it is important to maximize your design of production by reducing the labour time and cost incurred so as to ensure that you meet your daily production target. Rockwell refers to a tester instrument used in measuring the hardness of different materials and metals such as aluminium, zinc and iron using the Rockwell hardness scale. This method was developed and named after Stanley Pickett and it uses the principle of resistance to penetrate different materials.
How does it work?
The hardness test is carried out by using an indenter made of either steel or diamond into the surface of the material with a load and measures how far the indenter penetrates. It is important to note that there are different types of indenters and scales for different materials and you should choose the one that suits the material being tested the best. There are several factors to consider when choosing the best scale for your material and they include:
• Both the shape and size of the material.
• The limitation of the scale to be used.
What make it the best?
With its speed and a low amount of sample required it has a made this method to be adopted by so many people and companies globally. It displays the values immediately after penetration making it simple for people to use and above all it has become the most commonly used method.
When buying a tester it is important for you to clearly give your specification so that you will be given the best that will suit your needs.
