A rockwell hardness tester for sale is a vital tool in any metal shop. This type of device measures the strength of a metal alloy by forcing a diamond or steel ball indenter into the material and measuring the depth of the indentation created. This gives a number that identifies the hardness of the metal, allowing you to choose the best metal for your projects.
There are a variety of different types of hardness testers on the market. Each uses a different method of testing the materials, and each has its own advantages and disadvantages. The most common types of hardness testers are the Brinell and the Rockwell test methods. The Rockwell test uses a diamond cone to make the indentation, while the Brinell method uses a steel ball indenter to mark the surface of the material.
Another type of hardness tester is the ultrasonic test. This testing method utilizes sound waves to assess the quality of materials, allowing you to locate internal defects and identify cracks and other flaws in your materials. It’s important to note that this is a non-destructive testing technique, meaning it doesn’t damage or alter the material being tested.
Whether you’re looking for a benchtop or portable hardness tester, there’s sure to be a model that suits your needs. Some models offer a choice of either a regular or superficial Rockwell scale, while others have the capability to convert tests to other hardness scales, including Brinell, Vickers and Shore. You can also find testers that use a load cell or digital display, as well as a choice of loading capacities.
Grainger’s extensive selection of hardness testers makes it easy to find the right tool for your metalworking project. Choose a dependable analog or digital Rockwell tester to measure the hardness of a wide range of metals and plastics, including castings and forgings. Or, opt for a Brinell tester to measure the hardness of heavy metals and alloys. For smaller precision parts, thin materials or wires, a Leebs tester is an excellent choice.
