The hardness test of cemented carbide mainly uses Rockwell hardness tester to test HRA hardness value. PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry.
Cemented carbide is a kind of metal, and the hardness test can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, microstructure and heat treatment conditions. The correctness of the process and the research of new materials.
The hardness of cemented carbide is generally tested with Rockwell hardness tester HRA scale or Vickers hardness tester. In practice, people mainly use Rockwell hardness tester to test HRA hardness. PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. This instrument weighs only 0.7kg and has the same accuracy as a desktop Rockwell hardness tester.
