The DR-SW-20 series digital Vickers hardness tester for aluminum alloys (also known as the pliers-type hardness tester) is a portable instrument that can quickly test the hardness of aluminum alloys on-site. The test is rapid, simple, and can be completed with just one clamping. The hardness value is directly displayed. It complies with the Chinese non-ferrous metal standard YS/T420 and the American standard ASTM B647, and is one of the two instruments recommended by the standard YS/T420.
Main functions and features:
1.The aluminum alloy Vickers hardness tester is suitable for testing aluminum alloy profiles, tubes and plates. It is especially suitable for conducting rapid and non-destructive qualification checks on product hardness at production sites, sales sites or construction sites. ；
2. It can quickly and directly display the hardness tester's value on a digital screen.
3. The Vickers, Rockwell, Brinell hardness values and tensile strength values can be converted from the韦氏 hardness value.
4.Note: "Vickers hardness value" is translated as "Webster's hardness value" as it seems to be a specific type of hardness measurement, and there is no direct
Main uses and application scope:
1.Determine whether the workpiece has undergone heat treatment and inspect the effect of the heat treatment.
2. Determine whether the workpiece is made of an inappropriate alloy.
3. Test long or heavy workpieces or assemblies that are inconvenient to be sent to the laboratory.
4. For production inspection, acceptance inspection and quality supervision inspection
5. Mainly used for measuring the hardness of aluminum alloys (1100 to 7075 series)
