What materials are solid rivets commonly constructed from?

Solid rivets are frequently constructed from materials that possess high strength-to-weight ratios, corrosion resistance, and good ductility. Aluminium alloy, Monel, and titanium are particularly well-suited for aerospace applications where structural integrity and weight efficiency are critical.

Aluminium alloys are lightweight and commonly used due to their good mechanical properties and resistance to corrosion. Monel, a nickel-copper alloy, provides excellent corrosion resistance and is useful in environments exposed to sea air or chemicals. Titanium, known for its high strength and low density, is also advantageous in aircraft applications, particularly in high-stress areas.

These materials ensure that the rivets can withstand the stresses and environmental conditions found in aerospace applications. The other materials mentioned in the other choices either do not possess the required properties for aerospace standards or would be heavier and less effective in maintaining structural integrity in aircraft.
