Hardness Test

Best material strength is measured by its resistance to being indented or penetrated by its surface. The hardness test is very helpful in determining the best material to use since it gives a hardness value, which shows how easily a material can be machined and how well it will wear. Its definition is “resistance to indentation,” and its measurement is “permanent depth of the indentation.” Simply put, the smaller the indentation produced by a particular indenter and a fixed force (load), the harder the material is.

Brinell Hardness Test

This is one of the simplest ways to measure hardness. We press a tungsten carbide ball, either 5 or 10 mm in diameter, into the flat surface of your metal sample. Depending on the material, we apply a load ranging from 500 kg to 3000 kg for about 10 to 30 seconds. The size of the indentation left on the sample tells us how hard the material is.

Rockwell Hardness Test

The Rockwell test is all about measuring the difference in depth penetration between two loads. There are two types of Rockwell tests: Rockwell and Superficial Rockwell. The difference lies in the minor and major loads applied to the sample. Depending on the material, we use either a diamond cone or a hardened ball as the indenter.

Vickers Hardness Test

The Vickers test uses a rhombohedral-shaped indenter called the Knoop indenter. It’s particularly useful for testing materials with coatings or those with varying hardness levels across the surface. If you’re dealing with hard and brittle materials, this is the test for you.

Portable Hardness Test

When cutting a sample isn’t practical, like with large objects or when you need to test on-site, we use a portable digital hardness tester. This rebound-type tester lets us measure hardness without the need for a lab, making it perfect for those big or in-situ jobs.

Why It Matters:

Choosing the right material based on its hardness ensures your project runs smoothly, whether you’re machining parts, building structures, or developing new products. With Om Metalab’s Hardness Test services, you’ll have the confidence that you’ve picked the best material for the task at hand.
