The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester.

Stamping processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin plates, stainless steel plates, copper and copper alloys Plate, aluminum and aluminum alloy plate, etc non metallic fittings.

The portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are commonly used parts in the field of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips.

The main purpose of the hardness test of stamping parts is to determine whether the annealing degree of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts processing techniques require plates of different hardness levels.

The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester.
