Classification of hardness tester diamond indenter:
1. The standard indenter is used to calibrate the standard hardness block according to the national calibration regulations;
2. The working indenter is used to determine the hardness value of the specimen or sample in accordance with the national verification regulations;
3. The hardness alloy ball indenter is mainly composed of tungsten carbide and has a spherical indenter with a certain diameter;
4. A pressure head composed of a steel ball of a specified diameter and a pressure head body;
5. Steel ball or hard alloy ball indenter with diameters of 10, 5, 25, and 1mm for Brinell hardness tester;
6. The Rockwell hardness tester cone indenter has a cone angle of 120 degrees and a diamond cone indenter with a top spherical radius of 0.2mm. (Applicable to scales A, C, D, and N);
7. Rockwell hardness tester ball indenters with diameters of 1.588mm (for B, F, G, and J scales), 3.175mm (for E, H, and K scales), 6.35mm (for L and M scales), and 12.7mm (for R scale);
8. A regular four sided pyramid indenter made of diamond or industrial gemstones with an angle of 136 degrees between the two opposing faces of a Vickers hardness tester pyramid indenter;
9. A diamond quadrangular pyramid indenter with a relative angle of 172 degrees 30 minutes and 130 degrees for the Nusselt hardness pyramid indenter;
10. The intersection line between the two opposing sides of the cross edged pyramid indenter;
11. Shore hardness indenter symmetrical punch. A diamond indenter with a top spherical radius of 1.0mm;
12. The indenter of hardness testers such as Shore, Vickers, Babbitt, and International Rubber.
13. The Shore A hardness tester needle has a truncated cone with a cone angle of 35 degrees and a top plane diameter of 0.79mm;
14. The Shore D hardness tester uses a conical indenter with a cone angle of 30 degrees and a top spherical radius of 0.1mm;
15. The Vickers hardness tester has a truncated cone with a cone angle of 60 degrees and a top plane diameter of 0.4mm. This pressure needle is suitable for aluminum and aluminum alloys. A cylindrical indenter with a top plane diameter of 0.4mm, suitable for soft steel and hard aluminum;
16. A truncated cone with a cone angle of 26 degrees and a top plane diameter of 0.157mm for the indenter of the Babbitt hardness tester;
17. Micro rubber international hardness pressure needle with a steel ball pressure needle diameter of 0.395mm;
18. The punch is used in hardness testers such as Shore and Leeb to impact the components of the specimen;
19. The Leeb hardness tester punch, also known as the impact body, is made of tungsten carbide and diamond. Except for the E-type punch made of diamond, all other forms are made of tungsten carbide. There are six types: D, DC, D+15, G, E, and C. The G-type ball has a straight diameter of 5mm, while the other types have a ball head diameter of 3mm.
