In the aerospace industry, selecting the right materials for different applications is crucial to ensure maximum safety and efficiency. High among those typically selected are titanium and aluminum alloys.

Titanium, characterized by its high strength-to-weight ratio and superior corrosion resistance, becomes a popular material in many aerospace constructions. Key properties of titanium include lower density than steel but almost equal in terms of strength, high melting point, excellent high-temperature stability, and remarkable resistance against most acids and alkalis. For instance, aerospace engineers often use titanium alloy Ti-6Al-4V due to its exemplary fatigue resistance in wing structures and jet engines components.

Moving onto aluminum alloys, these offer unique benefits as well. Notably, they present excellent strength-to-weight ratios, good fracture toughness, and exceptional machinability. These attributes make them ideal choices for aircraft skin, fuselage, and engine components. An example use case within the aerospace sector is in the construction of commercial airplanes where series 2024 and 7075 aluminum are used extensively thanks to their combined characteristics of high strength and light weight.
