Both titanium and titanium alloys are perfect for aerospace applications simply because they can resist corrosion. Also, they are immune to any harsh environment condition, causing them to be an important part of aircraft parts. Their usage is limited because they are expensive as compared to other metals like steels and aluminum alloys, however.

As compared to steel, titanium is 50% lighter and 30% stronger. It is also twice stronger than aluminum but weighs 60% heavier. Titanium can withstand extreme heat, wherein it could stay even during temperatures exceeding 1,0008F.
To attain maximum strength and lighter weight, it is frequently alloyed with molybdenum, manganese, iron and aluminum. Its strong potential to deal with corrosion is a very important characteristic. When in contact with air, this metal forms an oxide film which can resist corrosive materials like water and salt.

Historical use
The titanium metal industry was primarily established to deal with the growing necessity of the aerospace industry inside the 1950s. During that time, titanium was applied in manufacturing aircraft hydraulic systems, airframe structural missiles, rockets and parts engine parts, and spacecraft.
Titanium is also utilized in many military applications as with artillery and guided missiles. In the 1970s, the expense of this metal substantially dropped, which made it more available for a number of other applications in shipbuilding. This industry used titanium for making propellers, other, rigs and shafts non-corrosive ship components. Also, because of its strength and hypoallergenic and lightweight weightstrength and properties, titanium became one of many metals used in the medical application industry. Additionally, using titanium was rampant within the petrochemical applications to transport oil and chemicals.
The impressive properties of titanium allowed it to turn into a popular metal for makingspacecraft and aircraft, naval ships, armor and missiles plates. For such applications, titanium is alloyed with vanadium and aluminum to boost its properties. The alloys formed from your mixture of these metals let them be made into helicopter exhaust ducts, landing gears, fire walls and structural parts. Also, these alloys could also be used in aircraft engines and airframes.
Titanium in aviation
Within the aviation history, the Blackbird SR-71 had become the first experimental aircraft to make use of substantial amount of titanium in the structure. A lot of modern commercial and military airplanes used the same concept, as a result. Boeing, a US-based aircraft manufacturer, used great deal of titanium in their commercial planes, wherein around 18 metric tons were used in 737, 45 in 747, and 59 in 777. It European competitor Airbus also used titanium among the aspects of its airplanes, wherein 12 metric tons were utilized A320, 18 in A330, and 32 within the A340. Its A380 super jumbo used 146 metric tons, in which 26 tons were used in the 4 engines. The A380 is definitely the latest commercial plane manufactured by Airbus. This double decker is currently regarded as the greatest commercial plane then the Boeing 747.
