Description of Titanium 5553 Master Alloy
In recent years, advancements in titanium alloy technology have enabled the development and use of alloys with high strength, high toughness and fatigue resistance. The Ti-5553 alloy is a representative example.
The Ti-5553 pre-alloy exhibits characteristics of both α+β and β titanium alloys. Its tensile strength in the annealed state reaches 1 080 MPa. After heat treatment in the duplex structure, its tensile strength exceeds 1 500 MPa, and it meets the specified fracture toughness requirements. Compared with the Ti-6Al-4V alloy, it offers improved hardenability, higher strength and enhanced fracture toughness. It has been used in the connection between the Airbus A380 wing and the engine pylon.
