What is titanium used for?

Titanium is a silvery-white metal, and the use of titanium to make aircraft only began in the 2050s. With the development of aviation and space industry, its use is more and more large, is the best material for the manufacture of aircraft, rockets, spaceships, missiles, satellites and so on. Titanium and titanium alloys are particularly good toughness, hardness can be comparable with steel, so their mechanical strength is significantly better than other alloy materials, comparatively speaking, are the most ideal high strength materials.

The density of titanium is relatively small, which is a light metal, only about half of that of steel. Using titanium alloy to replace the alloy steel widely used in the current aircraft structure can reduce the weight by about 40%. This is another advantage of titanium. Titanium is very stable at room temperature, not afraid of strong acid and alkali corrosion, corrosion resistance is the best performance of all metals, even if it is immersed in aqua regia, it does not care. Therefore, titanium alloy has stronger corrosion resistance than stainless steel. Titanium and titanium alloys also have a special crevice resistance. The same metal or not the same metal, as well as between metal and non-metal, connected together, the gap between them is often particularly easy to be corroded, resulting in the connection of the parts loose, the whole equipment is damaged. Such crevice corrosion can be avoided if titanium and titanium alloys are used. When the titanium alloy is welded, the performance of the titanium alloy is basically unchanged at the welded joint point. This is true even for thin sheets of titanium alloy. It takes tens of thousands of steel screws and rivets to put an airplane together. If replaced with titanium screws and rivets, in addition to the obvious weight reduction, fastening performance, welding performance and strength have been significantly improved. Someone ONCE MADE A TEST, AN AIRPLANE PASSES 1669 TIMES TAKE OFF AND LAND, FLIGHT TIME 1469 HOURS ABOVE, THE PERFORMANCE OF TITANIUM RIVET ON THE AIRPLANE IS STILL COMPLETELY GOOD.
