20HW Aluminum Alloy And Brass Hand Held Aluminum Hardness Testing Webster Hardness Tester
Webster hardness tester is a small handheld hardness testing instrument, it is small size, light weight, can be operated by one hand, can be fast, convenient, nondestructive testing material hardness such as aluminum alloy, brass etc, it does not need to sample calibration, the operating skills are not high, very suitable for the production site of the material for rapid hardness testing.
Main application of webster 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
Performance testing of webster hardness tester
1. Determine whether the aluminum profile has heat treatment, check
the heat treatment effect, determine whether the mechanical
properties of aluminum profile is qualified.
2. Determine whether the aluminum profile is processed with
inappropriate alloy and determine whether the aluminum profile
alloy composition is qualified.
3. Measure the long and heavy workpiece or assembly which is not
easy to send to the laboratory.
4. 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
