Malleable means it can be bent and shaped without breaking. Brass is a tensile metal used for smaller machines because it is easy to bend and mold into different parts. Its benefits over steel are that it is slightly more conductive, cheaper to purchase, less corrosive than steel, and still retains value after use. Brass is an alloy. Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization.
Because of this, iron is a good conductor. Platinum is an element with high electrical conductivity and is more ductile than gold, silver, or copper. It is less malleable than gold. The metal has excellent resistance to corrosion, is stable at high temperatures, and has stable electrical properties. Steel is a conductor and an alloy of iron. Steel is typically used to encase other conductors because it is an inflexible and highly corrosive metal when exposed to air.
It sees use in electrical contacts because, being a relatively soft metal, it deforms easily when tightened and makes a solid connection. For example, the connectors for car batteries are typically made of lead.

Conductive Order of Metals This list of electric conductivity includes alloys as well as pure elements. Gold is very expensive metal and is only used for certain materials like circuit board components or small electrical connectors.
Some materials are just gold plated to make them electric conductor. Silver : Silver, on the other hand, is more costly than other materials and is only used in advanced devices such as satellites or circuit boards. Silver is not commonly used for its conductive properties since it is a highly expensive and sought-after material.
Glass : Since the atoms have electrons that are tightly bound to each other, glass is used as an insulator. Brass : Brass is a tensile steel alloy, which makes it simple to bend and shape into various parts for smaller machines. It is less corrosive than steel, slightly more conductive, less expensive and maintains its value after use, while steel alloy is only useful when purchased firstly.
Aluminum works well but is risky to work with it, so it is not too common. Aluminum is actually more conductive than copper and its cost is also low. The reason why it is not too common is that it has numerous structural defects e. However, it is used in high-voltage transmission lines like phone cables which can be encased in steel for further shield. Steel is an iron alloy that is also a conductor. When exposed to air, it is extremely corrosive.
Steel is used to encase other conductors because it is difficult to cast and is not used in small devices. Graphite is a form of carbon that is an element. Graphite is a nonmetal and the only nonmetal that conducts electricity. Non-metals are found on the right side of the periodic table, and graphite is the only non-metal that is a good electrical conductor. All other nonmetals cannot conduct electricity.
This is due to the presence of free electrons, present in metals. Because the atoms in metals form a matrix through which outer electrons can freely move, metals are excellent conductors of electricity and heat. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the metal ions that are interacting.
Materials with high electron mobility are good conductors and materials with low electron mobility are not good conductors, instead referred to as "insulators.
While silver and gold are both effective, they are too expensive for common use. Individual properties make each ideal for specific purposes. Silver is the best conductor of electricity because it contains a higher number of movable atoms free electrons. For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
However, silver is more expensive than other materials and is not normally used unless it is required for specialized equipment like satellites or circuit boards. Copper is less conductive than silver but is cheaper and commonly used as an effective conductor in household appliances. Most wires are copper-plated and electromagnet cores are normally wrapped with copper wire. Copper is also easy to solder and wrap into wires, so it is often used when a large amount of conductive material is required.
Aluminum, when compared by unit weight, is actually more conductive than copper and costs less. Aluminum material is used in household products or in wiring but it is not a common choice because it has several structural flaws. For example, aluminum has the tendency to form an electrically resistant oxide surface in electrical connections, which may cause the connection to overheat. Aluminum is instead used for high-voltage transmission lines such as overhead phone cables which can be encased in steel for additional protection.
