Elevate your systems to new heights with the unmatched power and precision of Vickers Vickers hydraulic solutions. The average of the diagonal measurements is taken to get the single value to be used in the Vickers hardness test formula. In the world of materials science and metallurgy, Vickers Hardness Test is one of the processes used to determine material hardness. Hardness testing generally aids engineers in assessing the strength, durability, and wear resistance of a material. Vickers by Danfoss industrial valves give you their best day in, day out, in both stationary and mobile hydraulic applications. Vickers®, one of the most experienced and respected names in hydraulics, became part of Danfoss in 2021.
- {
- The indentation made by using the indenter must have a properly defined shape to be able to be measured.
- For example, the load applied ranges between 1 gf to 120 kgf, which depends on the material being tested.
- This indenter is applied onto the surface of the test material with force from a load, which ranges from a few grams to 100 kgf.
- In 1927, Vickers merged with Tyneside based engineering company Armstrong Whitworth to become Vickers-Armstrongs.
- The load is applied for a standard period of about 10 to 15 seconds, and the two diagonals of the indentation created are measured using a microscope.
- The hardness of a material can also be expressed in terms of the load used, for example, HV5 means the hardness calculated for a 5kg load.

Among all hardness testing methods, the Vickers test is preferred for sintered metal due to its precision and adaptability. This allows for accurate measurement of the matrix hardness while minimizing errors caused by surface porosity. Industrial applications require industrial-strength hydraulic systems—like those built with Danfoss piston pumps. A Vickers hardness tester is the ideal solution for precision hardness measurement of small, thin, or delicate materials.
What Is Vickers Hardness Test?
- {
- Calculating the hardness of the material is straightforward using the above mentioned formula, and the Vickers hardness is expressed in this form xxxHVyy or xxxHVyy/zz.
- A Vickers hardness tester is the ideal solution for precision hardness measurement of small, thin, or delicate materials.
- A Vickers hardness tester is used to measure the hardness of materials by applying a pyramid-shaped diamond indenter under a controlled force.
- The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.
- The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH).
- In 1960, the aircraft interests were merged with those of the Bristol, English Electric and Hunting Aircraft to form the British Aircraft Corporation (BAC).

The indenter used is diamond-shaped with a square base, and the opposite faces have an angle of 136° between them. This indenter is applied onto the surface of the test material with force from a load, which ranges from a few grams to 100 kgf. A Vickers hardness tester is used to measure the hardness of materials by applying a pyramid-shaped diamond indenter under a controlled force.
Vickers Hardness Tester – Understanding the Vickers and Knoop Hardness Test
In 1929, the acquired railway business was merged with that of Cammell Laird to form Metropolitan Cammell Carriage & Wagon. In 1928, the Aviation Department became Vickers (Aviation) Ltd and soon after acquired Supermarine, which became the “Supermarine Aviation Works (Vickers) Ltd”. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage & Wagon. In 1927, Vickers merged with Tyneside based engineering company Armstrong Whitworth to become Vickers-Armstrongs.

The Vickers hardness test is ideal for evaluating very small areas, thin materials, and coatings with high accuracy. With innovations spanning from alternative energy and civil engineering to manufacturing and marine, we’re one of the world’s most trusted industrial hydraulic solution partners. As a worldwide leader, Vickers Hydraulics designs and manufactures a comprehensive line of reliable, high-efficiency hydraulic systems and components. In 1960, the aircraft interests were merged with those of the Bristol, English Electric and Hunting Aircraft to form the British Aircraft Corporation (BAC). This was owned by Vickers, English Electric and Bristol (holding 40%, 40% and 20% respectively). The Supermarine operation was closed in 1963 and the Vickers name for aircraft was dropped in 1965.
Does the Shape and Material of The Indenter Affect the Accuracy of The Vickers Hardness Test?
The indentation made by using the indenter must have a properly defined shape to be able to be measured. The indenter is used to apply the load to the test sample for a dwell time of about 10 to 15 seconds. The Vickers test follows standards such as ASTM E384 or ISO 6507, and can be very useful for comparative studies. In 1921, the Vickers Hardness Test was developed by Robert L. Smith and George E. Sandland at Vickers Ltd. Vickers Hydraulic Valves are available with or without integral relief valve section and are suitable for pressures up to 3000 psi.

Even on the most exacting industrial applications, you’ll find our directional controls keep your maintenance simple and downtime at a minimum. Your choice of pump is backed by Vickers know how, assuring that you get the exact pump needed for the job. In 1919, the British Westinghouse electrical company was taken over as the Metropolitan Vickers Electrical Company; Metrovick.

Vickers was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law George Naylor in 1828. Naylor was a partner in the foundry Naylor & Sanderson and Vickers’ brother William owned a steel rolling operation. Edward’s investments in the railway industry allowed him to gain control of the company, based at Millsands and known as Naylor Vickers and Company. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems. Airflex industrial clutches and brakes are world-renowned for their superior performance, long life and high quality. In 1927, Vickers merged with the Tyneside-based engineering firm Armstrong Whitworth to form Vickers-Armstrongs.
