Knoop hardness test

Knoop hardness test

For any material scientist and process engineer, a Knoop microhardness tester is an indispensable piece of kit. These professionals require a Knoop microhardness tester to investigate and determine the hardness of different types of materials. Also known as the micro-hardness test, Knoop hardness test is one of the best methods to test for mechanical hardness, particularly for brittle materials. Knoop microhardness testing involves making a small indentation for testing purposes, making it the best way to test thin and brittle samples’ mechanical hardness.

Knoop microhardness testers and Vickers microhardness testers are more similar than not since they utilize a pyramidal indenter. However, the pyramidal indenter in a Knoop microhardness tester is a bit elongated compared to that of a Vickers microhardness tester.

When to Use Knoop Hardness Test

Knoop microhardness testing is perfect for determining the hardness of brittle and thin samples. In recent years, material scientists and process engineers use Knoop microhardness testers to evaluate the hardness of thin coatings.

Knoop microhardness testing involves applying the loading force and measuring the results on the surface of the test sample. Knoop microhardness testers give you a more precise evaluation since the longitudinal diagonal is longer for any indentation.

Through the Knoop microhardness testing, material scientists can determine mechanical phenomena such as creep characteristics, fracture toughness and hardness.


For customers seeking innovative products for hardness testing, a Knoop hardness tester is the ultimate choice. You can use a Knoop microhardness tester to evaluate and determine the hardness of various materials ranging from brittle to the most resilient samples.
