There are several hardness tests available in the market according to the type of test, the material of indenter, the type of sample, etc. Since the past few decades, there has been a surge in the market for the hardness testers.
What is the Brinell hardness method? Brinell hardness method is an optical method that works by measuring the intensity of indentation that is caused by an indenting material. Brinell hardness method applies an indenter that is spherical in shape, unlike the Vickers hardness method that applies the use of pyramid-shaped indenter that is pressed on […]
An object’s hardness should be classified as a feature or a characteristic rather than one of its properties and the hardness is generally measured by calculating the permanent area of the indentation caused by a fixed load.
For testing the hardness of metallic objects, there are a few methods, like the Rockwell hardness test, the Vickers hardness test, the Knoop hardness test, and the Brinell hardness test.
The Brinell method is one of the most popular and widely used techniques for measuring the hardness of a wide variety of specimens. The method has been named after J.A. Brinell who was its inventor in 1900. Hence, the Brinell test is the oldest method of hardness testing.
