Bismuth, as an example, has a very small thermal conductivity: approx. 8 W/m.K.
Metals are generally not absorbent; they are solid materials that do not absorb liquids or gases in the same way porous materials do. Instead, metals can conduct and reflect heat and electricity, and they can also form bonds with certain gases or liquids at their surfaces. However, some metals can absorb certain gases to a limited extent, but this is not the same as being absorbent in the traditional sense.

all metals are good conductors of heat and electric currents
Metals.
Copper, silver, and aluminum are considered some of the best heat conducting metals due to their high thermal conductivity properties. These metals are commonly used in heat sinks, electric wiring, and cooking utensils where efficient heat transfer is important.
We know that silver is the best heat conductor among the metals, followed by copper.

In general, metals are, indeed, better conductors of heat than other materials. There is one exception, however. The best conductor of heat we know of is an allotrope of carbon we call diamond. It is many times better than the best metals at conducting heat.
Silver, copper, gold are the best conductors of heat. In this order.
In general, metals conduct heat well. Silver, copper, gold and aluminum are among the best. Oddly, carbon in its diamond allotrope is the best conductor of heat we know of.
Silver is the best conductor of heat energy among common metals, as it has the highest thermal conductivity. Copper is also an excellent conductor of heat and is commonly used for heat exchangers and cooling systems.
