Aerospace Titanium Alloy Brief

High-Strength, High-Toughness Aerospace Titanium Alloys (β or Metastable β Type):

• Titanium alloys such as Ti-1023, Ti-15-3, β21S, and BT-22 exhibit superior strength and toughness.
• These alloys are characterized by their excellent combination of strength and ductility, making them suitable for demanding aerospace applications.

High-Temperature Titanium Alloys (Near α Type, Above 500℃):

• High-temperature titanium alloys like IMI834, Ti-1100, BT36, and Ti-60 maintain their mechanical properties at temperatures exceeding 500°C.
• They offer exceptional strength and thermal stability, enabling their use in high-temperature aerospace environments.

Damage Tolerant Titanium Alloys (α+β Type):

• Titanium alloys such as TC21 and TC4-DT possess enhanced damage tolerance due to their α+β microstructure.
• These alloys demonstrate excellent resistance to fatigue and crack propagation, making them suitable for critical aerospace components.

Flame Retardant Aerospace Titanium Alloys (Alloy C, BTT-l, BTT-3):

• Flame-retardant titanium alloys like Alloy C, BTT-l, and BTT-3 are designed to resist combustion and maintain structural integrity under fire conditions.
• They are essential for applications where fire safety is a priority, such as aerospace components exposed to high-temperature environments.
