ASTM B647 Aluminum Alloy And Brass Hand Held Aluminum Hardness Tester Mobile Hardness Tester
Introduction
A portable Webster hardness tester which can perform on-site hardness test on aluminum alloys. The test result can be got with only a simple clamp. It is convenient, efficient and reliable.
Webster hardness tester is the preferred instrument for testing aluminum alloys mechanical performance in accordance with American standard ASTM B647.
Used for quick test the hardness of aluminum profiles, tubing, sheets, accessories and other soft metal. Especially suitable for quick, non-destructive on-site 100% final products qualification test.
Webster hardness tester can be also used for testing hardness of copper, brass and soft steel.
The indenters of each type of Webster hardness testers are different. The shapes of three types of indenters are shown as Fig.below:
Main Technical Parameters
Testing Range: 0 - 20 HW (equivalent to 20 - 110 HRE, Model HHW-20)
Resolution: 0.5 HW (5 - 17 HW)
Repeatability: 0.5 HW (5 - 17 HW)
Weight: 0.5 kg
Features
Indenter: Re-engineered with advanced material and new production technology manufactured, higher hardness, long service life, good interchangeability.
Indicator Hand: High strength indicator hand, less likely to be bent by long-term using or mis-operation.
Dial Glass: High strength, high toughness, uneasy to be broken or scratched.
Handle: Forged aluminum alloy handle with fine anodized finishing, high resistance to abrasion and stain.
Hardness Blocks: Tested by standard rockwell hardness tester, the hardness block are attached with test report.
Stability: Stable full scale point, stable calibration point, indicator never glides.
Conversion: Results can be converted to Vickers, Rockwell and Brinell.
Models and Application
HHW-20: the most popular model, used to test normal aluminum profiles.
HHW-20A: used to test aluminum profiles with thickness within 13 mm.
HHW-20B: used to test aluminum tubings with inner diameter over 6 mm.
HHW-B75: used to test brass tubings and brass sheets.
HHW-BB75: used to test copper tubings and copper sheets.
HHW -B92: used to test soft stainless steel sheets, cold-rolled steel, etc.

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.
