In today's aerospace industry, materials aren't just chosen-they're engineered for performance. Titanium alloys, with their rare combination of light weight and high strength, have quietly become the backbone of many critical components, from aircraft engines to satellites orbiting the Earth.
Aerospace engines
The engine is a key indicator of aircraft performance and is known as the "metal heart" under high temperature and pressure. Titanium alloys, with high strength and low density, meet engine requirements for performance and weight reduction, playing key roles in multiple core parts.
Our country's TA32 titanium alloy has broken through the 600°C strength limit and is used in the high-pressure compressor blades of the Yangtze River CJ-1000 engine, reducing weight by 15% compared to traditional materials, marking a breakthrough in domestic aviation engine technology
01
Fuselage frame
Beams and bulkheads are the main load-bearing parts. Titanium alloy beams endure various flight loads, while their low density reduces energy use. Bulkheads maintain fuselage shape and stability, with strong corrosion resistance that reduces damage and maintenance.
02
Fuselage skin
The skin withstands aerodynamic forces and external erosion. High strength allows thinner skin to reduce weight, while corrosion resistance ensures stability in harsh environments and lowers maintenance. Advanced fighter jets use titanium alloy hot isostatically pressed integral skin to improve air tightness, strength and stealth by reducing joint gaps.

Fuselage connection
Bolts, rivets, and connectors are often titanium alloy, valued for high strength, toughness, and similar thermal expansion to connected materials. Its corrosion resistance prevents breakdowns and ensures machine safety and reliability.
Rockets and satellites
The Chang'e-6 lunar soil sample sealed container adopts a three-layer design, with the innermost layer being titanium alloy to protect the samples during storage and transportation.Titanium alloys are used in rockets' high-stress or high-temperature areas like engines and connectors, offering high strength to withstand loads and low density to reduce weight and enhance carrying capacity. They also appear in valves and pipelines inside rocket tanks.
In satellites, titanium alloys are used for structural frames, solar panel supports, and antenna structures. They are lightweight and thermally stable, ensuring structural integrity in space. The low thermal expansion reduces deformation from temperature changes, maintaining the geometric stability of solar panel brackets.
As aircraft fly farther and spacecraft reach deeper into space, titanium alloys continue to prove their value. Not just as a material, but as a driving force behind lighter, stronger, and more resilient aerospace designs.
