The processing of titanium metal is very complicated and the production cost is extremely high. Titanium is recognized as a non-toxic element in the world. The Handbook of Metals edited by the American Metal Society, an authoritative organization in the United States, points out: "Titanium and its compounds are almost inert to the human body physiologically, and titanium is the only metal that has no effect on the autonomic nerve and taste nerve of the human body." "Titanium ions do not transfer with blood and body fluids in human body." Because of its high and low temperature resistance, strong acid and alkali resistance, high strength and low density, titanium has become a special material for rockets and satellites of NASA, and has also been applied to super projects such as Yutu, J-20 and Shandong ship carrier. After entering the civil field in 1980s, it became the "honorary metal king" in the field of tableware with its natural antibacterial and biological characteristics.
The pure titanium thermos cup made of metallic titanium has the effects of resisting strong acid and alkali, inhibiting bacteria and keeping fresh, and can be used to hold various drinks, coffee, cola or traditional Chinese medicine. Titanium oxide has that temperature characteristic generate in the chemical synthesis treatment process, so that it become anatase crystal and is generated on the surface of titanium. The surface of titanium is an oxide film, which will not feel the rust smell of metal products and will not make the drink have an odor. The cup contains no harmful metals and trace elements. The unique "biology" of titanium material has no influence on human autonomic nervous system and taste, and there is no heavy metal precipitation, which can precipitate the aroma of the beverage to the greatest extent, make the taste of the beverage more mellow and keep the beverage fresh for a long time.
