Rockwell
Rockwell hardness testing is a general method for measuring the
hardness of metallic and polymer materials. Rockwell hardness
testing is an indentation testing method. The indenter is either a
conical diamond (brale) or a hard steel ball. Different indenter ball
diameters from 1/16 to 1/2 inch are used depending on the test
scale.
Hardness Testers
We offer a wide range of hardness testers for a variety of applications. These
machines can be supplied new or reconditioned.
We cover the complete range including Rockwell, Brinell, Vickers and Micro-
Vickers and Portable Hardness Testers. All machines come complete with a
warranty and calibration is available on-site
Brinell
The Brinell hardness test method as used to determine
Brinell hardness, is defined in ASTM E10. Most commonly
it is used to test materials that have a structure that is too
coarse or that have a surface that is too rough to be tested
using another test method, e.g., castings and forgings.
Brinell testing often use a very high test load (3000kgf) and
a 10mm wide indenter so that the resulting indentation
averages out most surface and sub-surface inconsistencies.
Hardness Tester Product Range
We supply all major types of hardness testers - Rockwell, Vickers, Brinell and
Universal which combine all the previous three types of hardness testers, together
with portable devices so that testing can be performed more conveniently.
Our commitment to you does not end once you have bought a hardness tester from
us. We can offer on-site service and calibration contracts to ensure your machine is
maintained in first class condition. Please contact us for further details..
Portable Testers
The Leeb rebound hardness test method was developed in 1975
by Leeb and Brandestini at Proceq SA to provide a portable
hardness test for metals. It was developed as an alternative to
the unwieldy and sometimes intricate traditional hardness
measuring equipment.
Traditional hardness measurements, e.g., those of Rockwell,
Vickers, and Brinell are stationary, requiring fixed workstations
in segregated testing areas or laboratories. The portability of
Leeb testers can sometimes help to achieve higher testing rates
without destruction of samples, which in turn simplifies
processes and reduces cost.
Universal Testers
As the name suggests, it is a machine that offers the measurement
of Rockwell Vickers and Brinell Scales. Due to its versatility it is
equipped with different types of indenter and measuring methods of
the indents created.
Peace of mind…
Hardness Testers supplied by Midland Metrology are covered by a 12 month warranty
for complete peace of mind.
Macro-Vickers
Macro Vickers is mostly used for small parts, finished
components and case depth work. The Vickers method is
based on an optical measurement system.
A square base pyramid shaped diamond is used for testing
in the Vickers scale. Typically loads are very light, ranging
from 5kg to 50kg.
Micro-Vickers
Micro Vickers is mostly used for small parts, thin sections, or case
depth work. The Vickers method is based on an optical
measurement system.
A square base pyramid shaped diamond is used for testing in the
Vickers scale. Typically loads are very light, ranging 10 grams to
1000 grams.
