A rockwell hardness tester for sale is a tool used to measure the strength and stiffness of material. This is done by using an indenter, usually a diamond cone or steel ball, to penetrate the surface of the material and mark it. The tool then measures the depth of penetration to determine how hard the material is. Several different testing methods exist for determining the hardness of materials.

Rockwell tests are the most common way to test hardness. They can be used on most metal alloys and can easily convert the hardness number into HB, HRB, HBW, HK and more. They also work well on a wide range of test surfaces, including cylindrical ones. However, this method can be time consuming and requires optical equipment to read the impressions made.

The Brinell method is another popular method of hardness testing. It uses a large steel ball to mark the surface of the sample, and it can be used on larger parts that are difficult to handle with other methods. However, the resulting impression can be less clear and the load required is high.

Vickers is another microhardness test technique that uses a narrow diamond-shaped indenter. It can be used on all solid and metallic materials and has a wide range of test loads, from 10 gf to 100 kgf. This test method is suitable for both soft and hard metals, although it may not be as accurate for steel and hard metals as the Rockwell or Brinell methods.

There are a variety of portable hardness testers for sale that use the Rockwell, Brinell or Vickers testing methods. These are much smaller and lighter than traditional benchtop hardness testers, making them more practical in most cases. They also typically include a rechargeable battery and digital display, which can help make them easier to use than many desktop models.
