AVIATION INDUSTRY

Aircraft building and aviation industry

Titanium and its alloys are commonly used in aviation industry, mainly due to their mechanical strength, thermal stability and immunity to corrosion. They are used to manufacture engine blades, structural components, suspension system and many other parts.

Molybdenum owes its popularity to high melting point, high stiffness, tensile creep resistance, good electrical conductivity and low thermal expansion coefficient. Unalloyed molybdenum is used, among other applications, for rocket nozzles. However, it is mostly used as alloying element. TZM alloy (Mo99-Ti0.5-Zr0.08-C0.02) is used for engine components working in elevated temperatures and exposed to heavy mechanical loads.

Tungsten is the second least fusible chemical element, it has a low thermal expansion coefficient and also shows high electrical resistivity in high temperatures. Due to its unique properties, it has become a very popular and common material in aviation industry. Tungsten is used for its properties such as high melting point, great fatigue properties and resistance to vibrations. It is mainly used for helicopter’s rotary blades, jet engine nozzles and balancing elements.

Nickel-based powders for 3D printing are becoming more and more prominent in the aviation industry. Inconel 625 alloy powder is suitable for production of engine exhaust systems, structural elements of wings and other engine parts. Inconel 718 alloy powder is used to make jet engine elements as well as components of liquid-propellant rockets.
