| AB9000 Automatic Brinell System Automatic Brinell hardness tester displays the hardness result without using a Brinell scope. Used for high volume testing without operator influence. Uses a Rockwell-type method with a standard Brinell ball and test load to read out directly in Brinell scales. | Portable Pin Brinell Lowest Cost Brinell Tester - the Pin
Brinell uses a calibrated shear pin to
control the amount of load applied.
Consistent loading regardless of
operator. Tests in 100 - 730 equivalent
Brinell range. |
Brinell Hardness Testers Operation:
The Test Method Widely used on castings and forgings, the Brinell test method applies a
predetermined test force (F) to a carbide ball of fixed diameter (D)
which is held for a predetermined time and then removed. The diameter
(d) of the indentation width is measured twice - usually at right angles
to each other and averaged. A formula or chart is then used to convert
the averaged measurements to a Brinell hardness number.
Test forces usually range from 500 to 3000 kilograms (occasionally down
to 1kg in less frequently used tests). Carbide* Brinell indenters are
10mm in diameter, although there are less frequently used tests with
light loads and smaller diameter indenters (from 5mm to 1mm). Generally,
the Brinell tester load must be held for 10 - 15 seconds although in
practice shorter dwell times are often used if it is known not to
influence the test result. The Brinell test measurement is typically
done to the nearest 0.05mm using a standard 20X Brinell scope. This
measurement is subject to operator influence.
