A periodic table element tile for titanium displays its atomic number 22, symbol Ti, atomic weight 47.867, electron configuration, and name. Icons indicate it is a solid, transition metal with a hexagonal crystal structure and equal relative strength. — titanium Properties of titanium.

Alpha-beta titanium alloys are widely used because they offer a favorable combination of strength, toughness, and formability.1

These alloys are one of four primary classes of titanium, categorized by the phases present at room temperature. By balancing alpha-stabilizing elements (such as aluminum) and beta-stabilizing elements (such as vanadium), manufacturers can achieve specific microstructural properties that make these materials highly versatile for various engineering applications.1

For example, the alloy Ti–6Al–4V is a prominent alpha-beta alloy developed for the aerospace industry. Due to its excellent strength-to-weight ratio and immunity to body fluids, it has also become a critical material for medical prostheses, such as hip-joint replacements.2
