In regards to titanium, what property contributes to its durability?

Titanium is known for its impressive strength-to-weight ratio, which plays a crucial role in its durability. Being lightweight yet comparable in strength to steel means that titanium can withstand significant stress and strain without sustaining damage. This combination of properties makes it particularly advantageous for applications where both lightness and strength are essential, such as in high-performance watches and aerospace components. The ability to resist deformation under load further contributes to its long-lasting durability, making titanium a preferred choice in industries that require robust materials.

The characteristics listed in the other options do not enhance durability; instead, they describe properties that would detract from the effectiveness and functionality of a material like titanium. For example, being weak or brittle would not contribute to overall durability, nor would being easily corroded. Thus, the argument supporting the strength and lightness of titanium as factors for its durability stands strong.
