The hardness test of the quality alloy mainly uses the Rockwell hardness tester to test the HRA hardness value. PHR series portable Rockwell hardness tester is very suitable for testing hard alloy hardness. The instrument's weight accuracy is the same as that of a bench Rockwell hardness tester. It is very convenient to use and carry.

Carbide is a kind of metal. The hardness test can reflect the difference in mechanical properties of hard alloy materials under different chemical compositions, organizational structures and heat treatment conditions. Therefore, the hardness test is widely used to test the performance of carbide and supervise the heat treatment. The correctness of the process and the study of new materials.


It is a non-destructive test and the test method is relatively simple. The hardness test of cemented carbide is more adaptable to the shape and size of the test piece, and the test efficiency is high. In addition, there is a certain correspondence between the hardness of hard alloy materials and other physical properties.

For example, hard alloy hardness tests and tensile tests are basically the ability to detect metal resistance to plastic deformation, both tests to a certain extent are similar to the detection of metal properties. Therefore, the test results are completely comparable to each other. Carbide tensile test equipment is huge, operation is complex, samples need to be prepared, and the test efficiency is low. For many metal materials, there is a conversion table of hardness test and pull test. Therefore, in testing the mechanical properties of hard alloy materials, people are increasingly using hardness tests, and less used tensile tests.


Carbide hardness is generally measured by Rockwell hardness tester HRA ruler or Vickers hardness tester. In practice, Rockwell hardness tester is mainly used to test HRA hardness. PHR series portable Rockwell hardness tester is very suitable for testing hard alloy hardness. This instrument weighs only 0.7kg and has the same accuracy as a benchtop Rockwell hardness tester.

When measuring hard alloy hardness, PHR series portable Rockwell hardness tester produced by Tianxing Company can test cemented carbide workpieces with thickness or diameter less than 50mm. It can test hard alloy workpieces with diameter as small as 2.0mm, and can test inner diameter smaller than 30mm tubular carbide workpiece. It can also be used at the production site, sales site or material warehouse.

This instrument is used to test hard alloy workpieces simply, quickly and non-destructively, and can perform piece-by-piece hardness testing on batches of finished or semi-finished carbide workpieces.
