Is Titanium The World's Most Recognised Non-toxic Precious Metal?

Titanium is recognised worldwide as a non-toxic element, named after the Titans of Greek mythology, and is expensive to mine and produce. The Handbook of Metals, edited by the American Society for Metals, an American authority, states, "Titanium and its compounds, are almost always physiologically inert to the human body, and titanium metal is the only metal that has no effect on the human vegetative and taste nerves." "Titanium ions do not transfer with the blood or body fluids in the human body." Due to a series of qualifications such as resistance to high and low temperatures, strong acids and alkalis, high strength, low density, etc., it has become a specialised material for NASA's same rocket satellites, and has also been used in China's super projects such as Jade Rabbit, J-20, and Shandong's aircraft carriers. In the 1980s into the civilian field, with its natural antibacterial and biophilic nature, it has become the "King of Honour Metal" in the food industry.
