Hardness Testers

Hardness Tester Hardness test or hardness test is one way to know the strength or technology (materials). Whereas violence itself (hardness) is one of the mechanical properties of materials other than its physical and technological properties. From the various references The formulas for the test are 4 (1) Brinnel (HB / BHN), (2) Rockwell (HR / RHN), (3) Vikers (HV / VHN) and (4) Micro Hardness (knoop hardness). Hard testing is the most effective material because it can be used easily. Even measurements are only done at a particular point or area. The violent values ​​it displays apply to material materials only.

Thus, the material can easily be classified as a ductile or brittle material.Hardness tester or used as Hard Test can also be used as material to know. Materials that have worked cold, hot, and hot, can be used with material strength. Therefore, with hard tests we can easily control the quality of materials.
