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 of Gaolue Precision Mould Company is the same as that of the desktop Rockwell hardness tester, which is very convenient to use and carry.
Cemented carbide is a metal. The hardness test can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, organizational structure and heat treatment process conditions. Therefore, hardness test is widely used in the inspection of cemented carbide performance, supervision of the correctness of heat treatment process and research of new materials.
It is a non-destructive test with a relatively simple test method. The hardness test of cemented carbide has strong adaptability to the shape and size of its test piece, and the test efficiency is high.
In addition, there is a certain correspondence between the hardness of cemented carbide materials and other physical properties. For example, cemented carbide hardness test and tensile test basically test the ability of metal to resist plastic deformation. These two tests are to some extent to test similar properties of metals.
Therefore, the test results are completely comparable to each other. The hard alloy tensile test equipment is large, complicated to operate, requires sample preparation, and has low test efficiency. For many metal materials, there is a conversion table between hardness test and tensile test.
