Cobalt chrome is a commonly used material in dental prosthetics due to several significant properties that make it suitable for this application. The properties specifically highlight the strengths of cobalt chrome as a dental material, such as its high modulus of elasticity, which ensures that restorations maintain their shape under stress, and its good biocompatibility, meaning it is well-tolerated by the body and does not provoke adverse reactions.

While cobalt chrome is known for its rigidity, which contributes to the durability and longevity of dental prostheses, it is not typically characterized by ease of repair. In fact, repairing cobalt chrome components can be quite challenging due to its hardness and the specifics of the metallurgical processes involved. This property requires specialized techniques or additional tools to ensure a proper bond or repair, making it less convenient compared to other materials that may be easier to manipulate or fix.

Thus, the aspect of cobalt chrome that isn't a typical property is its ease of repair, which is why this is the correct answer in the context of understanding its characteristics relative to dental applications.
