Metal Hardness Testing

Metal Hardness Testing

Metals hardness testing is the measure of how resistant a solid matter is to permanent shape change when an indenter is applied at a known force. When testing metals, the indentation hardness correlates linearly with the tensile strength of the material.

The greater the hardness of the metal, the greater resistance it has to deformation. Depending on the application and the type of material, many scales are available to suit your requirements. Rockwell Hardness Testing scales (ASTM E18) uses the depth of penetration of a preload versus the depth of penetration of a major load by a diamond or ball shaped indenter.

Brinell Hardness Testing (ASTM E10) is common for non-uniform type materials and uses the highest load and largest size ball type indenter. Vickers and Knoop hardness testing (ASTM E384) are performed using a diamond shaped indenter and are most commonly used for small parts, thin sections or case depth analysis.

Portable Hardness Testers

Portable hardness testing allows for on site and field production testing on a wide variety of metals and specimen configurations. Portable hardness testers are available in a variety of scales including Rockwell, Brinell, Vickers, Leeb and Webster.

Rockwell Hardness Tester

Rockwell Hardness Tester

Rockwell Hardness Testing is an indentation hardness that measures the depth of penetration after undergoing a preload followed by a major load. Rockwell testing is generally used for quality control of steels and other alloys (including some plastics).

Brinell Hardness Tester

Brinell Hardness Tester

Brinell Hardness Testing is an indentation hardness that measures materials that are too coarse or have too rough of a surface for other hardness methods. A carbide ball is pressed into a material at a defined load for a defined time and the resulting diameter of indentation is measured.

Vickers and Knoop Hardness Testers

Vickers and Knoop Hardness Testers

Vickers Hardness Testing is an indentation hardness that can be used for all metals. A diamond penetrator is used for both Micro Vickers (0-1kgf) and Macro Vickers (1-100kgf) which allows for the Vickers Hardness value to be continuous over the complete load range.
