Introduction :

W-20 series aluminum alloy Vickers hardness tester (also known as clamp hardness tester) is a lightweight instrument that can quickly test the hardness of aluminum alloy on site. The test is quick and easy, one card can be used, and the hardness value is directly read out. It conforms to the Chinese non-ferrous standard YS/T420 and the American standard ASTM B647. It is one of the two instruments recommended by the standard YS/T420.
W-20 series aluminum alloy Vickers hardness tester is suitable for testing aluminum alloy profiles, pipes and plates. It is especially suitable for rapid and non-destructive inspection of product hardness at the production site, sales site or construction site. The standard hardness block is tested by a standard hardness machine with a test report. The Vickers hardness value can be converted into commonly used Vickers, Rockwell, Brinell hardness and tensile strength values.

Application :

1. Determine whether the workpiece has heat treatment and check the heat treatment effect.
2. Determine if the workpiece is machined from an improper alloy.
3. Used to measure excessively long, heavy workpieces or assemblies that are inconvenient to be sent to the laboratory.
4. Can be used for production inspection, acceptance inspection and quality supervision inspection
