Microhardness testing is a method of determining a material’s hardness or resistance to penetration when test samples are small, thin, or dealing with composite samples in small regions. Microhardness testing can provide precise and detailed information about surface features of materials that have a fine microstructure. However, there are some common problems that can arise when microhardness testing. We are going to go over common problems with microhardness testing, and their causes. For a lot of engineers, scientists, and testers, three terms often come into their minds when talking about microhardness testing: finicky, subjective, and time-consuming. Now, advances in computer... Continue reading

Non-destructive testing (NDT) is used to analyze material properties and/or the structural integrity of a material without causing any damage to the material that is being tested. It is used in a wide variety of industries and fields including oil and gas, aerospace, automotive, structural engineering, university test labs, etc. Metsuco has been supplying these industries with non-destructive testing supplies for over 30 years. With that being said, we wanted to introduce to you a few of the manufacturing companies whose NDT products we carry. Each one of these companies has made a name for themselves in the industry and...

Since 1900, there have been widely accepted methods of hardness testing metal and other materials using hardness testers. The different scales and methods include Vickers, Brinell, Rockwell, Shore, and nondestructive methods of ultrasonic hardness testing.  Hardness testers and hardness testing equipment have been one of our staple product offerings here at Metsuco for over 30 years. With that being said, we wanted to introduce to you a few of the manufacturing companies whose hardness testing products we carry. Each one of these companies has made a name for themselves in the industry and we are proud to carry their products.... Continue reading

In previous posts, we have talked about the differences between the different hardness tests, such as Vickers, Rockwell and Brinell. However, we haven’t talked as much about comparing the scales and what makes them different. Here we want to go more into comparing the hardness scales themselves. First though, a quick word about testing methodology. These different scales are measured by using different hardness testing equipment and methodology, but Vickers, Rockwell and Brinell and even Shores have one thing in common, they are all measuring the hardness by indentation. Whether it’s the carbide ball of a Brinell Test or the... Continue reading

Hardness in manufacturing and engineering is defined by resistance to indentation, and it is determined by measuring the permanent depth of the indentation; which is known as a hardness test. Brinell Hardness Test was the first used and is a widely accepted hardness test. In this article we are going to dig a little deeper into explaining the Brinell Hardness Test. J.A. Brinell proposed first proposed the hardness test in 1900. Brinell's desire to have a consistent and fast means of determining material hardness grew during his involvement in several Swedish iron companies. The concept he proposed was a steel...
