Titanium Bar for Aerospace

Titanium bar have the advantages of low density, high strength, high temperature resistance and good corrosion resistance, and have been widely used in the aerospace field.

1.Introduction of titanium bar for aerospace

Titanium bar have the advantages of low density, high strength, high temperature resistance and good corrosion resistance, and have been widely used in the aerospace field. U.S. military fighters in the 1970s used titanium alloys at a quarter of the structural weight. Since the 1970s, titanium tactical missiles, satellites, launch vehicles and other aerospace products have gradually gained The application. At present, titanium alloys have developed into the most promising metal structural materials in the design and production of modern aerospace industry.

6. Application of titanium bar for aerospace

The American Timet company developed the Ti1023 titanium bar in 1971. The nominal composition of the alloy is Ti-10V-2Fe-3Al. Under normal use, σ_b≥1100MPa, KIC≥60MPa • m^{1 / 2}, which is by far the most widely used one. High-strength, high-toughness near β-type titanium alloy is a deformed titanium alloy with high structural efficiency, high reliability and low manufacturing cost, which is adapted to the principle of damage tolerance design. The alloy has been used in Boeing 777 passenger aircraft landing gear main beam, A380 main landing gear support and other components.

In various advanced military fighters and bombers designed by the United States after the 1980s, the amount of titanium bar has stabilized at more than 20%. For example, the third-generation fighter F-15 titanium alloy accounts for 27%, while the fourth-generation fighter F-22 titanium alloy accounts for 41%.
