Whether you’re an industrial manufacturer or a metalworker, a rockwell hardness tester for sale is an invaluable tool in your arsenal. These innovative devices are designed to measure the strength and stiffness of a specific metal using an indentation technique that is applied directly to the surface of your sample. Whether you’re looking for a Rockwell, Brinell or Vickers tester for your operation, the right tool can help you increase your productivity and reduce the risk of quality issues within your production line.
Choosing the best model for your needs
Hardness testing equipment comes in many different shapes and sizes, from large-scale floor-mounted units to handheld digital models. The most common hardness testers use the Rockwell method and can directly measure the hardness of steel, cast iron and non-ferrous metals. These instruments can also convert the results of a standard Rockwell test into HB, HV, HB-C and HK values.
These machines can be used for both static and dynamic testing. Dynamic testing involves measuring the movement of sound waves in a material to detect defects or imperfections within the structure of the piece. This type of inspection is non-destructive and a great choice for larger parts that cannot be easily transported or tested in-house.
Static testing is a more traditional method that measures the hardness of a sample by applying pressure to the indentation created by the tool. This is a time-consuming process, however, and requires special optical equipment to read the impression on the material’s surface.
A more advanced alternative to these types of testing is the Leeb hardness tester, which uses a diamond indenter to create an impression on the material’s surface. This method can be used to evaluate the hardness of soft-bearing metals and carbides, and may even be able to determine the case depth in steel samples. Leeb hardness testers are smaller, lighter and more portable than most other types of hardness testing devices, making them ideal for field work.
