BT22 Titanium Alloy: Aerospace-Grade Material for High-Performance Applications
BT22 Titanium (Ti-5Al-5Mo-5V-1Cr-1Fe) is a high-strength and high-toughness titanium alloy designed for aerospace and heavy industrial applications. Known for its excellent mechanical properties, BT22 is often used in high-stress aerospace components, landing gear, and engine parts where strength and reliability are paramount.
What is BT22 Titanium Alloy?
What is BT22 Titanium Alloy?
BT22 Titanium is a near-beta titanium alloy, also known as Ti-5Al-5Mo-5V-1Cr-1Fe. It offers high strength and hardness, especially in the annealed state, making it ideal for aircraft components that require excellent fatigue resistance and corrosion protection. The alloy's bimodal microstructure provides a perfect balance of toughness, ductility, and strength, ensuring that it performs well under extreme mechanical loads.
Excellent combination of high strength + relatively low density (compared to steels) → good for weight-sensitive structures. Good corrosion-resistance (benefit of titanium alloys) plus performance due to alloying and processing. Capability for large components (plates, forgings) means versatile for structural use. The development of surface/processing treatments (wear resistance studies) indicates good future potential.
