Difference between rockwell and brinell hardness test
Answers
Explanation:
The Rockwell hardness is based on difference of indentation depth of indenter from two different load applications. First minor load is applied to achieve zero level then major load is applied for specific period.p
Brinell hardness (HBW) is the ratio between the applied force and the surface of the print. Indenter is a hard metal ball, with a diameter D that is imprinted by force F into the surface layers of the material. The diameter of the ball is standardized and amounts to: 10; 5; 2.5; 1mm.

Answer: A 10mm hardened steel ball is used in the Brinell hardness test, whereas the Rockwell test, depending on the material being evaluated, either employs a considerably smaller steel ball (4mm) or a diamond cone. While the Brinell test evaluates the width of the depression, the Rockwell test assesses its depth.
Explanation:
Step :1 All kinds of metals can be tested with a Brinell hardness tester. Because the Brinell method uses a spherical indenter to properly distribute pressure, its results are more precise and trustworthy than those produced by the Rockwell method.
Step: 2 Compared to the Brinell or Rockwell tests, this test is performed more accurately and with less force. Unlike a Rockwell machine, it employs a diamond indenter that is significantly smaller. The optical equipment used in the Vickers test allows for magnification of the material's target region. It is the oldest technique still in use in many hardness testers today. It is frequently used to gauge the thickness of objects with rough surfaces, including castings and forgings, where it yields the most precise measurements. It is well known that Macro makes Brinell hardness testers.
