Non-ferrous metals offer several distinct advantages in mechanical systems, which is why identifying all of their benefits as an option is appropriate. Higher conductivity is a significant trait of non-ferrous metals, particularly with materials like copper and aluminum. These metals are commonly used in electrical applications because they allow electricity to flow efficiently with minimal resistance, making them ideal for wiring and connectors.

Lower weight is another notable advantage, especially with metals like aluminum. This characteristic is critical in applications where reducing the overall weight of the structure or machinery can lead to enhanced performance and fuel efficiency, such as in the automotive and aerospace industries. Non-ferrous metals thus provide a good strength-to-weight ratio, which is beneficial in many engineering contexts.

Resistance to corrosion is another critical attribute of non-ferrous metals. Unlike ferrous metals that can rust and degrade in moist or reactive environments, non-ferrous metals such as aluminum, copper, and titanium exhibit remarkable resistance to various forms of corrosion. This property ensures a longer service life and reduced maintenance costs for components made from these materials, making them well-suited for applications in harsh conditions.

By encompassing these attributes—higher conductivity, lower weight, and resistance to corrosion—it's clear that non-ferrous metals present significant advantages in mechanical systems, leading
