20HW Webster Aluminium Hardness Testing HUATEC Webster Hardness Tester
HUATEC brand Webster hardness tester is a small handheld instrument, it is small size, light weight, can be operated by one hand, can be fast, convenient, nondestructive testing metal material hardness, it does not need test sample, very suitable for the production site of the material for rapid hardness testing.
Main application of websler hardness tester
Webster hardness tester uses two different shapes of pressure
needle, two different test forces, their combination to form three
different models of instrument, respectively for aluminum alloy,
soft copper, hard copper, ultra hard aluminum alloy and soft steel.
The Wechsler hardness tester is suitable for testing materials with
two parallel surfaces, such as tubes, plates and profiles, up to
13mm in thickness.
The webster hardness tester is very suitable for testing batches of
products on the production site. Although its sensitivity is not
high, it has been able to meet the requirements as a production
control and conformity determination instrument. It is for this
reason that vickers hardness tester has been widely used in the
aluminum processing industry.
Webster hardness tester on the market is mainly HHW-20 series
aluminum alloy Wechsler hardness tester, as well as used to detect
copper alloy Wechsler hardness tester
Testing performance
1. Test whether the aluminum profile has heat treatment, check the
heat treatment effect, determine whether the mechanical properties
of aluminum profile is qualified.
2. Test whether the aluminum profile is processed with
inappropriate alloy and determine whether the aluminum profile
alloy composition is qualified.
3. Test the long and heavy workpiece or assembly which is not easy
to send to the laboratory.
4. Popular equipment used for aluminum production inspection,
acceptance inspection and quality supervision and inspection.
5. The reading is convenient and can be easily converted into other
hardness values. The measuring range is mainly used for measuring
aluminum profiles and aluminum alloy materials, but also can
measure copper alloy materials. Its measurement range is equivalent
to: aluminum profile :24~110HRE copper alloy :60~90HRF
6. Can measure a variety of aluminum profiles.
7. The operation is simple and the operation skill has no influence
on the reading.
The indenters of each type of Webster hardness testers are
different. The shapes of three types of indenters are shown as

Operating Method
Put the specimen between the anvil and the indenter and press down the handle until thebottom is felt. At the time the dial indicator will point at a reading which is the hardness valueobtained. Excessive pressure beyond this limit will not damage the tester, but it is unnecessary.Hold tight the handle when reading the value. Any torsion or movement will make the reading incorrect during the test.
