Titanium
Titanium is very often used in aviation, cosmonautics, healthcare and jewelery due to its properties, especially low weight, hardness and high corrosion resistance. For these industries, which do not include such a large area as machinery and electrotechnics, is titanium too expensive. Nevertheless, it is possible to mark titanium if necessary. The marking behavior is very close to stainless steel, the color of the markings is influenced by the addition of energy (heat) to the material surface.
