rockwell hardness tester for sale for sale provide an efficient and cost-effective way to measure the strength or stiffness of a wide variety of metal alloys. The test method measures the penetration of a harder tool (usually a diamond cone or steel ball) into the material and the resulting impression it leaves on the surface. There are a number of different tests and corresponding scales to choose from, making it important to choose the right one for your application. This guide offers an overview of the various options available to you.
We stock a comprehensive range of bench-top and portable hardness testers that use the Brinell, Rockwell and Vickers methods. We have a model for almost every requirement. Choose from models that can measure Rockwell hardness, or ones that convert to other scales such as HB, HV, and HK. Some are designed specifically for testing metals, while others can also be used to test soft-bearing materials such as ceramics or composites. Our hardness testers are suitable for a wide variety of industries including aerospace, automotive, and military applications.
Why Choose a Rockwell Tester?
A Rockwell hardness tester is the most commonly used type of tester, and offers a broad testing range. These units are designed to work with both diamond indenters and steel indenters, depending on the type of sample being tested. A high level of accuracy is ensured by using a standard test load and by ensuring that the indenter is pressed into the surface of the sample with a straight angle.
The Rockwell test is ideal for metals, ranging from very soft metals to carbides. It also can be used to test other solid materials. The test results are obtained by measuring the size and depth of the impression made on the surface of the sample, and the corresponding hardness values are determined from the relationship between the peak height and the smallest diameter of the indentation.
The Vickers method is another microhardness testing technique. It is a more accurate and reliable method than the Rockwell method, as the use of a spherical indenter distributes pressure evenly, which results in a legible impression on the sample surface. The resulting hardness values are then compared to the standard Vickers hardness scale.
