Stamping parts hardness testing method

The hardness test of Metal Stamping parts is tested by a Rockwell hardness tester. Stamping parts processing uses dies to separate or form metal sheets. It is used in a wide range of applications and is one of the commonly used parts in metal processing, machinery manufacturing and other fields. Stamping parts processing mainly includes processing procedures such as punching, bending, stretching, forming and finishing. The main purpose of hardness testing of stamping parts processing materials is to determine whether the degree of annealing of the purchased metal sheet meets the subsequent standards for stamping parts processing. Because of the different types of stamping processing processes, the required plate hardness levels are also different. Among them, the aluminum alloy sheet used for stamping parts processing should be tested with Vickers hardness, and if the thickness of the material is greater than 13mm, it should be tested with a Bartz hardness tester. The materials for stamping parts processing are mainly hot-rolled and cold-rolled, and mainly cold-rolled metal sheet materials such as carbon steel sheet, tin-plated sheet, galvanized sheet, copper and copper alloy sheet, aluminum and aluminum alloy sheet.
