Which element has highest thermal conductivity?
Diamond – 2000 – 2200 W/m•K. Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.

What is liquid thermal conductivity?
Thermal conductivity of liquid is high, so it can take away a major portion of the heat at zero flow conditions and naturally sensitivity suffers; From: Plant Flow Measurement and Control Handbook, 2019.
Is oil thermally conductive?
Thermal conductivity for the crude oils is rather insensitive to changes in temperature for temperatures from 273 to 323 K. For two of the oils, the thermal conductivity is approximately 120 mW/(m K), while for the other it is approximately 130 mW(m K) over the quoted 50 K temperature range.

What does high thermal conductivity mean?
Thermal conductivity, frequently represented by , is a property that relates the rate of heat loss per unit area of a material to its rate of change of temperature. Materials with a higher thermal conductivity are good conductors of thermal energy.
Which metal has the highest thermal conductivity?
Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. Silver is used in a very broad range of applications, including, but not limited to, jewelry, coinage, electrical and electronic devices, and photographic compounds.
Which is the best thermal and electric conductive material?
As a result, metals like silver and copper are a few of the metals with this particular characteristic. That is why they are great electric and thermal conductors. Copper – In conclusion, copper like silver, only has one valence electron which makes this metal very conductive. Therefore, one of the more popular commercial applications is the coating of high-end cookware and kitchen appliances.
What are the best conductive metals?
