Titanium Aerospace Metals
Both titanium and titanium alloys are best for aerospace applications simply because they can resist corrosion. Also, they are safe from any harsh environment condition, which makes them a significant component of aircraft parts. However, their usage is limited because they are expensive as compared to other metals like steels and aluminum alloys.

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

Historical use
The titanium metal industry was primarily established to deal with the growing need of the aerospace industry in the 1950s. During that time, titanium was applied in manufacturing aircraft hydraulic systems, airframe structural parts, rockets and missiles engine parts, and spacecraft.
Titanium is additionally used in many military applications as in artillery and guided missiles. In the 1970s, the expense of this metal substantially dropped, which made it more readily available for various other applications in shipbuilding. This industry used titanium for making propellers, other, rigs and shafts non-corrosive ship components. Also, due to its strength and hypoallergenic and light weightstrength and properties, titanium became among the metals found in the medical application industry. Additionally, using titanium was rampant within the petrochemical applications to move oil and chemicals.
The impressive properties of titanium allowed it to become popular metal to makespacecraft and aircraft, naval ships, armor and missiles plates. For such applications, titanium is alloyed with vanadium and aluminum to bolster its properties. The alloys formed from your mixture of these metals allow them to be produced 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
Inside the aviation history, the Blackbird SR-71 took over as the first experimental aircraft to use substantial amount of titanium in its 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 the commercial planes, wherein around 18 metric tons were utilised in 737, 45 in 747, and 59 in 777. It European competitor Airbus also used titanium as among the components of its airplanes, wherein 12 metric tons were utilised A320, 18 in A330, and 32 within the A340. Its A380 super jumbo used 146 metric tons, in which 26 tons were utilized in the 4 engines. The A380 will be the latest commercial plane manufactured by Airbus. This double decker is now regarded as the greatest commercial plane followed by the Boeing 747.
