Which Metals Conduct Heat Best? As copper is an excellent conductor of heat, it’s good for heat exchangers, heat sinks, and even saucepan bottoms. Because steel is a poor conductor of heat, it’s good for high-temperature environments like airplane engines. Here are some important applications which require metals that conduct heat well:

- Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper.

What materials make good conductors ? · just now. Report Abuse. Electrical conductors: Pure metals and the best conductors. Copper is the most common material for electrical wiring, and gold for high-quality surface-to-surface contacts,the reason is that it prevents corrosion because it doesn't react with Oxygen.ost metals are good conductors, gold is good but expensive, copper is another and relatively inexpensive. Many multi layer ceramic ceramic capacitors, used in electronics, use palladium.

Lessons In Electric Circuits -- Volume I Most familiar conductors are metallic. Copper is the most common material used for electrical wiring. Silver is the best conductor, but is expensive. Gold is used for high-qua … lity surface-to-surface contacts. Aluminium too is a good conductor.ater and metal are the two most well known conductors. They are conductors because they let electricity flow through them.

Good and bad conductors of heat Good and bad conductors of heat. Most metals are good conductors of heat; silver and copper are exceptionally good. On the other hand, substances such as cork, wood, cotton and wool are bad conductors. Both good and bad conductors have their uses. The “bit” of a soldering iron is made of copper, so that when its tip is cooled through contact with the work, heat is rapidly conducted from the body of the bit to restore the temperature of the tip and maintain it above the melting-point of solder.

- The molecules with a higher movement collide with the less energized molecules and transfer part of their energy to the less energized molecules of the colder regions of the structure. For example, the heat transfer by conduction through the bodywork of a car. Metals are the best thermal conductors; while non-metals are poor thermal conductors. For comparison, the thermal conductivity (k) of the copper is 401 W/m*K, while the thermal conductivity (k) of the air is 0.0263 W/m*K.

- the heat sink puts stress on the motherboard, which the motherboard is generally designed to accept. So the aluminum is a nice because it adds very little stress and weight to the motherboard. One of the best materials that are used for heat sinks is copper. Coppers thermal conductivity is nearly double that of Aluminum at 400 W/mK.

Which material is very good conductor of heat but bad conductor of electricity? Rubber is a good conductor if heat but a bad conductor if electricity. Diamond will do the first two IIRC, but its intrinsic strength is much higher than stainless steel. However its failure modes are very different, so comparing the two is a bit thankless.... mika.
