MATERIAL DEFINITION
The most confusing subject in material selection is the conversions between hardness scales. Soft coppers and castings are usually measured with Brinell (HB), while thin sheets and precision surfaces use the Vickers (HV) scale.
In hardened tool steels (like Silver Steel), the Rockwell (HRC) standard is essential. Digital hardness testers in the Point Metal quality laboratory measure in all three scales accurately and record them in analysis reports.
Engineers should note that conversion tables are only an estimate, not 100%; the physical structure of the material directly affects the measurement result. Our technical team supports you in determining the most accurate hardness test method for your alloys.

FAQ
Q. Will there be conversion errors?
A tolerance of 5-10% should be left in conversion tables according to material structure.
