Eggwell W-20 Vickers hardness tester

Eggwell W-20 Vickers hardness testerAluminum alloy Vickers hardness tester (also known as clamp type hardness tester) is a lightweight instrument that can quickly test the hardness of aluminum alloys on site. The testing is fast, simple, and can be done with just one card. The hardness value can be directly read out, which complies with the Chinese non-ferrous standard YS/T420 and the American standard ASTM B647. It is one of the two recommended instruments for the YS/T420 standard. W-20 type is suitable for testing aluminum alloy profiles, pipes, and plates, especially for rapid and non-destructive qualification inspection of product hardness at production, sales, or construction sites; W-20A can be used to detect industrial aluminum profiles, plates, and parts with a thickness of up to 13mm; W-20s are used to test small aluminum profiles and aluminum pipes with an inner diameter greater than 6mm. The standard hardness block has been tested by a standard hardness machine and comes with a test report. The Vickers hardness value can be converted into commonly used Vickers, Rockwell, Brinell hardness and tensile strength values.
