Titanium alloy plates for aerospace applications are core materials in modern aircraft manufacturing, and the choice of grade directly affects aircraft performance. The following is a professional-level introduction:

I. Core Grades and Characteristics

α-Type Titanium Alloys

TA1/TA2: Industrially pure titanium, highly corrosion-resistant, used in wing de-icing systems.

Ti-5Al-2.5Sn ELI: Excellent low-temperature performance, maintaining toughness even at -250℃, used in rocket engine impellers.

Near-α Type Titanium Alloys

Ti-6Al-4V (Grade 5): High strength, corrosion-resistant, accounting for over 45% of titanium production, used in engine blades.

Ti-6Al-2Sn-4Zr-2Mo-0.08Si: Stable at 540℃, used in compressor blades.

β-Type Titanium Alloys

Ti-10V-2Fe-3Al: High strength, used in Boeing 777 flap rails.

Ti-15V-3Cr-3Sn-3Al: Tensile strength 1100 MPa, used in fuselage structures.

II. Technology Trends

Surface Treatment: Sandblasting and anodizing improve wear resistance.

Forming Process: 3D printing enables integrated complex structures.
