Titanium Aerospace Metals


Both titanium and titanium alloys are perfect for aerospace applications because they can resist corrosion. They are also safe from any harsh environment condition, making them an important element of aircraft parts. Their usage is limited because they are expensive as compared to other metals like steels and aluminum alloys, however.4140 steel

Titanium is 50% lighter and 30% stronger, as compared to steel. It is also twice stronger than aluminum but weighs 60% heavier. Titanium can withstand extreme heat, wherein it could stay even just in temperatures exceeding 1,0008F.

To accomplish maximum strength and lighter in weight, it really is frequently alloyed with molybdenum, aluminum, iron and manganese. Its strong resistance to corrosion is a very important characteristic. When subjected to air, this metal forms an oxide film which may resist corrosive materials like water and salt.

Historical use

The titanium metal industry was primarily established to address the growing need for the aerospace industry within the 1950s. During that time, titanium was used in manufacturing aircraft hydraulic systems, airframe structural parts, rockets and missiles engine parts, and spacecraft.

Titanium can also be used in many military applications like in artillery and guided missiles. Inside the 1970s, the expense of this metal substantially dropped, which made it more available for various other applications in shipbuilding. This industry used titanium in making other, shafts, rigs and propellers non-corrosive ship components. Also, because of its strength and hypoallergenic and light weightproperties and strength, titanium became one of many metals utilized in the medical application industry. Furthermore, using titanium have also been rampant in the petrochemical applications to transport oil and chemicals.

The impressive properties of titanium allowed it to turn into a popular metal in makingaircraft and spacecraft, naval ships, armor and missiles plates. For these applications, titanium is alloyed with vanadium and aluminum to boost its properties. The alloys formed from the mixture of these metals permit them to be produced into helicopter exhaust ducts, landing gears, fire walls and structural parts. Also, these alloys may also be used in aircraft engines and airframes.

Titanium in aviation

Within the aviation history, the Blackbird SR-71 became the first experimental aircraft to make use of substantial quantity of titanium in its structure. As a result, a lot of modern commercial and military airplanes used the same concept. Boeing, a US-based aircraft manufacturer, used great amount of titanium in the 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 used A320, 18 in A330, and 32 inside the A340. Its A380 super jumbo used 146 metric tons, which 26 tons were utilised in its 4 engines. The A380 is the latest commercial plane manufactured by Airbus. This double decker is now viewed as the largest commercial plane accompanied by the Boeing 747.
