【CYPRESS –Titanium alloy-Relief Sculpture】 Titanium alloy is a 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. 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. Every knock mark on the barrel, every relief, is hand-painted by the designer, carefully crafted, and gives warm hand-made marks on the cold metal. After such layers of tempering, we finally present such a gorgeous and dazzling fine art!
