Titanium was discovered in 1791, but it wasn’t distilled into its pure form until General Electric employee M.A. Hunter did so in 1910. And it wasn’t until the 1930s that William J. Kroll invented a process to extract the element on an industrial scale.
Although steel (carbon, alloy or stainless) is the primary fastener material used in aerospace, titanium is used when its advantages relative to steel are essential for a given application. The most common titanium alloy used for aerospace fasteners is TI-6Al-4V.
Titanium Aerospace Fastener Characteristics
Titanium exhibits higher tensile strength than other materials, even at increasing temperatures. Titanium aerospace fasteners are also extremely resistant to seawater and galvanic corrosion, so are found in many aeronautical and naval applications. Because they have moderate ductility and low work hardening rate, they are not ideal for every application.
It’s twice as strong as aluminum, but only 60 percent heavier.
Titanium Aerospace Fasteners are used for…
Titanium aerospace fasteners are used in a limited number of applications where their high strength to weight ratio, excellent resistance to stress corrosion cracking, high corrosion resistance, and good fatigue strength are desired.
- – Military and commercial maritime applications
- – Submarine masts and exteriors
- – Landing gear and engine components (aviation)
- – NASA launch vehicles and spacecraft
- – Commercial and military satellites
