The hardness of metal stamping parts is measured by Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop Rockwell hardness testers.
Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.
Portable surface Rockwell hardness testers are ideal for testing the hardness of these stampings. Alloy stampings are commonly used parts in the field of metal processing and mechanical manufacturing. Stamping processing is a processing method in which a metal strip is separated or formed by a mold.
The main purpose of the hardness testing of stamping materials is to determine whether the degree of annealing of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts processing processes require sheets of different hardness levels. The aluminum alloy plate used for stamping processing can be tested by a Vickers hardness tester. When the material thickness is greater than 13 mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should be a Barcol hardness tester.
