Titanium is a very special metal. It is very light in texture, yet very tough and corrosion-resistant. It retains its own color for life at room temperature. The melting point of titanium is similar to that of platinum, so it is often used in aerospace and military precision parts. After adding electric current and chemical treatment, different colors will be produced. Titanium has excellent resistance to acid and alkali corrosion. Titanium that has been immersed in "aqua regia" for several years is still bright and radiant. If titanium is added to stainless steel, only about one percent is added, which greatly improves the ability to resist rust.
Titanium has excellent characteristics such as low density, high temperature resistance, and corrosion resistance. The density of titanium alloy is half that of steel and the strength is almost the same as that of steel; titanium is resistant to high temperatures and low temperatures. It can maintain high strength in a wide temperature range of -253℃~500℃. Metal processing WeChat, the content is good and worthy of attention. These advantages are necessary for space metal. Titanium alloy is a good material for making rocket engine shells, artificial satellites, and spacecraft. It is called "space metal". Because of these advantages, titanium has become a prominent rare metal since the 1950s.
