I. Purpose
SW-20 series digital display Webster hardness tester Aluminum alloy Webster hardness tester (also known as clamp hardness tester) is a portable instrument that can quickly test the hardness of aluminum alloys on site. The test is quick and easy, just one card, and the hardness value is displayed directly. Determine whether the workpiece has heat treatment, check the effect of heat treatment; determine whether the workpiece is processed from an inappropriate alloy; test long, heavy workpieces or assemblies that are inconvenient to send to the laboratory; used for production inspection, acceptance inspection and quality supervision inspection ; Mainly used to measure the hardness of aluminum alloys (1100~7075 series).
2. Features
Aluminum alloy Webster hardness tester is suitable for testing aluminum alloy profiles, pipes and plates, especially suitable for quick, non-destructive qualification inspection of product hardness on production sites, sales sites or construction sites; it can quickly and directly display the hardness tester ; Webster hardness value can be converted into commonly used Vickers, Rockwell, Brinell hardness and tensile strength values;
