Titanium cups are cups made of titanium metal. It took more than 100 years from the discovery of titanium to the preparation of pure products. The real use of titanium, and the realization of its true colors, is something after the 1940s. Titanium has good heat resistance and a melting point of up to 1668°C. At room temperature, titanium can lie in a variety of strong acid and alkali solutions unharmed. Even the most ferocious acid, aqua regia, cannot corrode it. Titanium is not afraid of sea water. Someone once sank a piece of titanium to the bottom of the sea. Five years later, when it was taken up, there were many small animals and underwater plants stuck on it, but it was not rusted at all, and it was still shiny.

The advantages of titanium are simply: light, hard, and rust-free. Although the specific gravity of titanium is two-thirds of that of steel, it has the same strength and excellent corrosion resistance. In the past, most of this speciality was used in the equipment of jet aircraft and artificial satellites. In recent years, with the research and development, it has been found that it is harmless to the human body. Since the new century, it has been widely used as a new material in the medical field, decorations, etc. attention from all walks of life.
