Customer Reviews
The touch screen micro vickers hardness tester has been installed a few weeks ago, everything is OK. Thanks for your advice and excellent service.

—— Mr. David Chambers

Thanks for the fast delivery and our customer is very satisfied for the rockwell hardness tester, and hope more orders soon.

—— Neil Renato

After we visited the customer, they finally decided to purchase Brinell hardness tester iBrin-413Z, now we have installed the unit at customer’s site,

Thank you for the indenters (diamond  cone 120 degrees). We recently got it and already tested it. Indenters  are good as we expected.

What is Rockwell Hardness Test ?
What is Rockwell Hardness Test ?


The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).

 

The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.

 

What is Rockwell Hardness Test ?

 

The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.

 

Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).

 

High Rockwell hardness numbers represent hard materials and low numbers soft materials.
