Hardness test of Aerospace Micro Screws materials

2025,07,26
The main purpose is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent Aerospace Micro Screws processing. Different types of Aerospace Micro Screws processing technologies require plates of different hardness levels.

The aluminum alloy plates used for Aerospace Micro Screws processing can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead. Pure aluminum plates or low-hardness aluminum alloy plates should use a Barcol hardness tester.
In the Aerospace Micro Screws industry, stamping is sometimes also called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method of using sheets, thin-walled tubes, thin profiles, etc. as raw materials for plastic processing, which is collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.
