【CYPRESS –Titanium alloy-The Starry Night】 Our metal pen-making has entered a new field. In addition to maintaining the high-class texture of the metal, we also need to think about how to change the color and texture pattern on it, so we launched a pen designed with titanium alloy! Titanium alloy with good comprehensive mechanical properties and high specific strength. The specific strength of Titanium alloy is 23.5, while the specific strength of alloy steel is less than 18. In addition, the elastic modulus of titanium alloy is low, and it is easy to deform during processing. When making titanium alloy pens, it is necessary to overcome technical difficulties skillfully, of course we are more than happy to take on the challenge! The manufacturing process of a titanium alloy pen is complicated, which can be briefly summarized into the following points for everyone to understand： First, we need to carve the pattern and polish it to make the brightness and texture obviously. After that, we must completely remove the body oil or other dirt attached to the metal with a special mixed liquid, so that the metal can be activated and colored better before entering the step of baking the color at a constant temperature, and then repeated grinding and polishing, and after the barrel is completed, thoroughly removed the metal residue and more than color blocks in the details once again, and air-dried in a dust-free room.
