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.

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.
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.
Certified Test Blocks are a requirement as a reference material for any type of hardness testing. At NextGen, we understand the importance of a Test Block to ensure the accuracy of your hardness testing procedures.

BringGen-3000 system comes standard with a manual measuring microscope. Once the indentation is made, the manual microscope is placed on top of the indentation and the operator uses the micrometers to align to the diagonals of the indentation. The reading is then input into the main unit using the touch-screen, user-friendly LCD screen and the machine in turn provides your Brinell hardness reading.
The CCD Optical Analysis upgrade for the Brinell hardness tester allows the operator to make the indentation, then simply place the CCD camera onto the indentation, and the automatic software will do the rest. The system will auto align the diagonals and provide you error free Brinell readings directly onto a PC. This eliminates the operator error factor and allows for additional export possibilities to Excel directly.
