HBS-62.5 Digital Display Small Load Plastic Aluminum Brinell Hardness Tester
HBS-62.5 digital display small load Brinell hardness tester is a
high-tech product of opto-mechanical integration. The machine has
novel shape, good reliability, operability and intuitiveness. It is
a new type of display device using precision mechanical technology
and optoelectronic technology. Micro Vickers and Knoop hardness
tester.
The machine adopts computer software programming and optical
measurement system. Through soft key input, you can choose
different indenter and force value measurement, can adjust the
strength of the measurement light source, can choose the dwell
time, can display the indenter diameter, test force, measurement
range, and direct reading on the screen on the LCD display. The
hardness value is obtained, which simplifies the tedious look-up
table. It is easy to use, and the measurement accuracy is higher
due to the use of a rotary encoder.
Due to the large pressure used in the Brinell hardness test, the
large ball diameter of the indenter and the large indentation
diameter, it is suitable for the hardness measurement of metal
materials with large grains. Such as cast iron, non-ferrous metals
and their alloys, after various annealing and tempering treatments,
and most of the steel delivered from the factory, this instrument
selects a part with a relatively small Brinell hardness value, so
it is especially suitable for softer metals. Such as pure aluminum,
copper, lead, tin, zinc, etc. and their alloys, the measured
hardness is very accurate, and the Brinell hardness has high
measurement accuracy, so it has good reproducibility and
representation.

1. What is Brinell hardness tester?
The Brinell hardness tester uses the oldest method of hardness testing commonly used today. It was invented in Sweden by Dr. Johan August Brinell in 1900. This test is often used to determine the hardness of castings and forgings whose grain structure is too course for accurate Rockwell or Vickers testing.
2. What do you perform a Brinell hardness test?
Brinell Hardness Test Procedure
In this test method, a predetermined force (F) is applied to a tungsten carbide ball of fixed diameter (D) and held for a predetermined time period, and then removed. The spherical indenter creates an impression (permanent deformation) on the test metal piece.

3. How does a hardness tester work?
A hardness test is typically performed by pressing a specifically
dimensioned and loaded object (indenter) into the surface of the
material you are testing. The hardness is determined by measuring
the depth of indenter penetration or by measuring the size of the
impression left by an indenter.
4. How do you read a Brinell microscope?
Manual reading is easy and straightforward. You look through the
lenses, focus the optics, position in the lens on the impression
and read the result in mm. The result in mm is then converted to
HBW (Hardness Brinell) by looking up the mm measurement and the
table provides the hardness.
5. What is the difference between Brinell and Rockwell hardness
test?
The Brinell hardness testing uses a 10mm hardened steel ball, while
the Rockwell test uses either a much smaller steel ball (<4mm)
or a diamond cone, depending on the material being tested. The
Rockwell test measure the depth of the indentation, while the
Brinell test measures the width of the indentation.
6. What indenter is used for Brinell test?
spherical indenter
In the Brinell hardness test, an optical method, the size of
indentation left by the indenter is measured. In contrast to the
likewise optical Vickers method,which involves a pyramid-shaped
indenter being pressed into a specimen, the Brinell method uses a
spherical indenter.
7. How do you find the Brinell hardness number?
The Brinell hardness number (BHN) is calculated by dividing the
load applied by the surface area of the indentation. Figs.
6.72–6.74 show some of the Brinell hardness test sites.
