Abstract Titanium alloy has been widely used for aerospace fasteners industry due to its low density, high yield strength, and good corrosion resistance. The research and prospect of titanium fasteners are reviewed. Nationally and internationally, the recent development and application of titanium fasteners are introduced. The tensile properties of some candidate alloys for high-strength fastener application are summarized and compared. Some high-strength β-titanium and the technical processes of bar or wire for fasteners are introduced on the basis of requirement for advanced aircraft.
