Brinell Hardness Testing

Brinell hardness testing is a method of accurately measuring the hardness of different types of materials.

The process involves pressurized force – by pressing a tungsten carbide ball or a steel ball (chromium plated) right against the material.

The test is conducted under stringent test conditions and the amount of pressure applied ranges from 300 to 3000-kg for five to twenty-five seconds.


Brinell Hardness Testing and its Applications

The significance of hardness testing to evaluate the flexibility, strength, and durability of metals cannot be understated.

Industries that require Brinell Hardness Testing are:

  • General metal equipment manufacturers
  • Mining Industry
  • Aerospace Industry
  • Construction Industry
  • Major steel and aluminum producers
  • Automotive Industry

The hardness of a material does not necessarily indicate the strength of the material. In fact, it is the measurement of how resistant the material is to indentation.

To find this, a fixed force is applied to the metal and depending on the level of the indentation, big or small; it determines the true hardness of the material.

The ability of a material to resist bending, deformation, cutting, abrasion or scratching requires that any material, before it is used for manufacturing, undergoes a Brinell hardness test to ensure that it can withstand the force and pressure it will need to endure.

To ensure that the metals provided to manufacturers are of top quality standard and strength, they are tested on a regular basis. By completing the Brinell Hardness testing, manufacturers are assured of the required hardness of the metals, and they can proceed with utilizing them for their manufacturing purposes.

Process for Brinell Hardness Testing

We offer services with quick test results that you can get within a 2 to 3-day turnaround.

The test itself, however, is performed as per the requirements of our NATA Accreditation as the force applied is critical for accurate results.

Industry-experienced and competent tradespeople oversee and perform all the Brinell hardness tests.

Reliance Hexham is an accredited NATA (National Association of Testing Authorities) laboratory, conforming to ISO/IEC 17025 General Requirements for the Competence of Testing and Calibration Laboratories, and brinell hardness testing conducted at our facility is completed in accordance with the Australian standard AS 1816.1.  NATA accredited certification can be supplied for brinell hardness testing and is also supported by our certified quality management system.
