Titanium is a good metal

The metal titanium has good corrosion resistance and high strength. Titanium's low density makes it an ideal structural material for use in aerospace, medical devices, automobiles, and sporting goods. It is characterised by being lightweight and strong, and is therefore used in a wide variety of applications.
Titanium is an excellent metallic material, and its low density, high strength, and resistance to high temperatures and corrosion make it widely used in aerospace applications. Titanium alloy is only half as dense as steel but nearly as strong, which makes it one of the necessary materials for space metals. Titanium alloys also maintain high strength under extreme temperature conditions, which makes it play an important role in the construction of spacecraft and aircraft. Overall, titanium's excellent properties make it one of the ideal materials for many high-tech fields.

Titanium alloys are also ideal for the manufacture of rocket engine housings, satellites and spaceships, and are therefore known as the "space metal". Due to its high corrosion resistance and stability, titanium does not cause allergic reactions when it comes into contact with the human body, and is therefore known as a "biophilic metal", with no effect on the human vegetative nerve or sense of taste.
However, titanium is relatively difficult to extract, mainly because at high temperatures it reacts with oxygen, carbon, nitrogen and other elements. Despite the relatively high content of titanium in the earth's crust (about 6 per cent of the weight of the earth's crust, more than 10 times more than copper, tin, manganese and zinc combined), its extraction and processing is still a challenging process.
