What are titanium alloys?

Titanium alloys are composite metallic materials based on titanium, mixed with alloying elements like aluminum, vanadium and molybdenum to enhance mechanical performance. They feature extremely high specific strength, meaning they are far lighter than steel while maintaining equivalent load-bearing capacity. A stable passive oxide film naturally forms on their surface, offering strong resistance to seawater, chloride solutions and weak acid corrosion. The material keeps stable performance under cryogenic conditions up to 550°C, making it a vital lightweight structural material widely adopted in high-end manufacturing fields with strict weight and anti-corrosion standards.
