Aerospace Industry

Aerospace manufacturing, particularly aerospace engine manufacturing, is distinctive among other high-volume manufacturing industries. The engine is the most complex component of an airplane, housing the most individual components and determining fuel efficiency in the end. The introduction of lean-burn engines, which can reach temperatures of 3,800°F, has boosted the demand for novel materials. Given that current superalloys have a melting point of roughly 3,360°F, the challenge is discovering materials that can endure higher temperatures.

Materials Used in the Aerospace Industry

Heat-resistant superalloys (HRSAs), which include titanium alloys, nickel alloys, and even nonmetal composite materials like ceramics, are currently being used to meet temperature needs. Aluminum alloys, high-strength steels, titanium alloys, and composites are the most widely recognized commercial aerospace structural materials, accounting for more than 90% of the weight of airframes.


Titanium alloys capable of performing at temperatures ranging from sub-zero to 600°C are used in engines for shafts, blades, discs, and casings from the front fan to the last stage of the high-pressure compressor, as well as in lightly loaded fabrications like plug and nozzle assemblies at the rear end of the engine. Titanium currently accounts for up to 10% of the empty weight of aircraft such as the Boeing 777. Titanium is also used in engine applications such as compressor blades, rotors, and hydraulic system components.

Titanium’s properties make it an ideal material for usage in the aircraft industry. Aerospace applications, by their very nature, necessitate parts that are both light and strong. Titanium is highly corrosion-resistant in addition to having a favorable weight-to-strength ratio. Titanium generates a passive oxide coating when exposed to air or pure oxygen at high temperatures. The titanium is protected from oxidation and other forms of corrosion by this passivating coating.

Titanium 5553 (Ti-5553) is a relatively new metal in the aerospace industry, with high strength, lightweight, and excellent corrosion resistance. This titanium alloy is ideal for major structural components that need to be stronger and lighter than the previously employed stainless steel alloys.

Titanium 6Al-4v is one of the most used grades of Titanium in the aerospace market.   Depending on the application, various forms are available including plate and sheet (AMS 4911) and rectangular and round bar.

Flight Metals offer various grades of Titanium in a variety of shapes and sizes, including plate, round bar, block, sheet, and tube, as well as a variety of heat treatment conditions. We can provide the required grade with applications spanning from aerospace to automotive to desalination.


Aluminum tubing is used in the fuselage, hydraulic system, and fuel line of aircraft and automobiles. In the warehouse, Flight Metal has a complete line of aluminum bars, plates, rectangular bars, and sheet items. We can provide a quick turnaround for our customers’ customization.

Alloy Steel

Steel alloyed with elements such as silicon, manganese, chromium, molybdenum, nickel, vanadium, and boron is known as alloy steel. With alloy steels of various compositions, hundreds of products can be made: alloy steel pipes and tubes, alloy steel sheets, plates, and coils, alloy steel rods, bars, and wires, alloy steel buttweld fittings, alloy steel forged fittings, alloy steel, fasteners, flanges, and other alloy steel products. Automobiles, road construction, machinery and equipment, buildings, mining, railways, appliances, and off-shore applications are a few of the industries in which alloy steels are used.
