Stamping Hardness Testing Methods
Nov 16, 2017

Usually the hardness of metal stamping parts is measured by Rockwell hardness tester. But small and complex hardware stamping test surface is very small, and there is no way to test on the ordinary desktop Rockwell hardness tester. The processing of stamping parts using mold makes the metal strip separation or forming of a processing method, it is applied widely, is one of the most commonly used parts in metal processing, mechanical manufacturing and other fields.

The main materials for hot stamping are hot rolling and cold rolling, and cold rolled strip, such as carbon steel plate, tin plate, galvanized sheet, copper and copper alloy plate, aluminum and aluminum alloy plate. Stamping parts mainly include blanking, bending, stretching, forming and finishing processing program.

The main purpose of stamping material hardness testing is to determine whether the annealing degree of the purchased metal plate meets the standard of stamping parts to be processed. And because of the different types of stamping process, the required plate hardness level is not the same. Among them, the aluminum alloy sheet used for stamping processing is to use Vivtorinox hardness testing, and the thickness of the material if more than 13mm, to use the hardness tester for testing.
