Beta-titanium alloys are primarily characterized by their high strength and elasticity, which makes them ideal for orthodontic applications. The significant components of these alloys typically include titanium along with alloying elements such as molybdenum and zirconium. Each of these elements contributes to the mechanical properties and performance of the alloy, with molybdenum improving strength and zirconium enhancing corrosion resistance.

Aluminum, while it is a common alloying element in certain titanium alloys, is not a significant component in beta-titanium alloys specifically. The main purpose of utilizing beta-titanium alloys in orthodontics is to leverage their unique properties, which are best achieved through the presence of titanium, molybdenum, and zirconium rather than aluminum. Therefore, aluminum does not play a crucial role in the makeup of beta-titanium alloys, distinguishing it from the other elements listed.
