As an expert in the field of materials science, I can provide you with a detailed explanation on the metals that are conductors of electricity.

Electrical conductivity is the measure of a material's ability to conduct an electric current. Metals are known for their high electrical conductivity due to their atomic structure. The outer electrons of metal atoms are loosely held and are free to move, which allows them to transfer electric charge easily.

Copper is one of the most widely used conductors due to its excellent electrical conductivity, which is surpassed only by silver. It is used extensively in electrical wiring and components because of its high ductility, allowing it to be drawn into thin wires, and its resistance to corrosion.

Silver is the best conductor of electricity among all metals. However, due to its high cost and limited availability, it is not commonly used for large-scale electrical applications. Silver is often used in high-precision devices where its superior conductivity is crucial.

Aluminum is another good conductor of electricity, although not as efficient as copper. It is lighter and less expensive than copper, making it a popular choice for power transmission lines. Aluminum's conductivity is about 61% that of copper, but its lower density can make it advantageous in certain applications.

Gold is known for its excellent resistance to corrosion and its ability to maintain conductivity over time. It is used in high-reliability connectors and in the plating of electrical contacts to prevent tarnishing and ensure a good electrical connection.

Steel is not as good a conductor as the metals mentioned above. It is an alloy primarily composed of iron and carbon, with other elements added to improve its properties. While steel is not typically used for its electrical conductivity, it can be used in certain applications where its strength and durability are more important than its electrical properties.

Brass, which is an alloy of copper and zinc, has good electrical conductivity but not as high as pure copper. It is often used for its corrosion resistance and strength in applications such as electrical fittings and connectors.

In summary, the metals that are the best conductors of electricity are copper, silver, and aluminum.
Gold is used for its reliability and resistance to corrosion, while steel and brass are not as conductive but can be used in specific applications where their other properties are more important.
