β-type titanium alloys offer a unique combination of properties for springs. Their high strength, low elastic modulus, low density, and good corrosion resistance result in springs designed to be both smaller and lighter and more corrosion resistant than springs made of other materials. Design considerations, along with mechanical and fatigue properties, are discussed for a Ti–3Al–8V–6Cr–4Mo–4Zr alloy. Examples of applications are included.
