Why is Aluminium a better conductor of heat than magnesium? Answered by Charlie M. Answered by Raisha A. Answered by Chris M. Payment Security. Aluminum is often used in satellite dishes. Gold is also known for its high conductivity, but because of its cost, it is only used in moderation.

Microchips may have gold wires for connections and, where applications require high resistance to oxidation and corrosion along with high conductivity, very thin gold plating is used. When it comes to metal alloys, their physical properties can improve the main metal in areas such as strength, durability, withstanding environmental conditions, and electrical applications. For example, brass — an alloy of copper — is also used to conduct electricity. Though not known for electrical conductivity, different grades of stainless steel still have important electrical applications.

Type and Type are the most common grades used in the electrical industry for its superior resistance to corrosion. Electrical enclosures for wall-mounts, floor mounts, and freestanding junction boxes are made with stainless steel. Quest-Tech knows that choosing the right metals for a job can make all the difference, whether electrical or for other requirements.

Iron Conductivity Iron has metallic bonds which is where the electrons are free to move around more than one atom. Platinum Conductivity Platinum is an element with high electrical conductivity and is more ductile than gold, silver, or copper.

Steel Conductivity Steel is a conductor and an alloy of iron. Stainless Steel Conductivity Stainless steel is a relatively good conductor of electricity, as are all metals.

Factors That Affect Electrical Conductivity Certain factors can affect how well a material conducts electricity. ThoughtCo explains these factors here: Temperature: Changing the temperature of silver or any other conductor alters its conductivity.

In general, increasing the temperature causes thermal excitation of the atoms and decreases conductivity while increasing resistivity. The relationship is linear, but it breaks down at low temperatures. Impurities: Adding an impurity to a conductor decreases its conductivity. For example, sterling silver is not as good of a conductor as pure silver.

Oxidized silver is not as good a conductor as untarnished silver. Impurities hinder electron flow. Crystal structure and phases: If there are different phases of a material, conductivity will slow slightly at the interface and may be different from one structure than another. The way a material has been processed can affect how well it conducts electricity. Electromagnetic fields: Conductors generate their own electromagnetic fields when electricity runs through them, with the magnetic field perpendicular to the electric field.

External electromagnetic fields can produce magnetoresistance, which can slow the flow of current.
