CD pattern screws are generally made of stainless steel

As a person who frequently purchases mobile phone CD pattern screw, the material quality of CD pattern screws is basically the industry default. Why is the mobile phone CD pattern screws made of stainless steel? Carbon steel, titanium, aluminum material is not good? Below we will briefly analyze the advantages of using stainless steel CD screws. And why the mobile phone CD pattern screw do not use carbon steel material:

Let’s see what the CD pattern screws looks like:

The mobile phone CD pattern screw is obviously different from the ordinary screw. It is brighter and more glossy than ordinary screws. And it can also reflect different brilliance. This is a circular groove of the circle left by the laser head during machining.

The material quality requirement of CD pattern screws is that the plasticity is medium, the plasticity of the material is too low, and the surface of the CD-shaped screw that is etched will have brittle cracks to expand. If the plasticity is too high, the adhesive action will occur, just like the surface knives. Similarly, it is necessary to change the combination performance of the material by the vacuum heat treatment process before the CD-shaped screw can be processed. Stainless steel is the best choice.
