W-20 series aluminum alloy Vickers hardness testerDetailed product description：

Overview

The W-20 series aluminum alloy Vickers hardness tester (also known as a 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 ASTMB647. It is one of the two recommended instruments for the YS/T420 standard.

The W-20 series aluminum alloy Vickers hardness tester is suitable for testing aluminum alloy profiles, pipes, and plates, and is particularly suitable for rapid and non-destructive qualification inspection of product hardness at production, sales, or construction sites.
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.

purpose
*Determine whether the workpiece has undergone heat treatment and check the heat treatment effect.
*Determine whether the workpiece is machined from an inappropriate alloy.
*Testing of excessively long or heavy workpieces or assemblies that are difficult to deliver to the laboratory.
*Used for production inspection, acceptance inspection, and quality supervision inspection.
