Which characteristic is not typically found in metals used for mechanical applications?

In the context of metals used for mechanical applications, low strength is not a typical characteristic. Metals are generally valued for their high strength, which allows them to withstand various loads and stresses without deforming or breaking. This high strength is crucial in mechanical applications, where components need to maintain integrity under pressure and during operation.

On the other hand, high thermal conductivity, ductility, and electrical conductivity are characteristics commonly associated with metals. High thermal conductivity allows metals to efficiently transfer heat, which is important for processes such as machining and in applications where heat dissipation is critical. Ductility refers to the ability of metals to deform under tensile stress, which is essential for forming processes such as bending and shaping. Lastly, electrical conductivity is key for metals used in electrical applications, making them ideal for wiring and components that require efficient electrical conduction.
