They're called conductors. As opposed to insulators, which don't conduct. Metals are typically pretty good conductors.
Semiconductor
Materials that transfer thermal energy well are called good themal conductors. The metals are generally good conductors of heat (thermal energy).
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
They are called insulators. Rubber is an example of a good electrical insulator.More:PlasticGlassAirWoodCeramicPorcelainPaperVarnishMineral OilSlateMarblePolyethyleneSiliconePVCKaptonTeflon

Semiconductor
Materials that can conduct heat are called good conductors of heat and electricity. Most of the time, these materials are metals. Nonmetals are not good conductors of heat.
Materials that transfer thermal energy well are called good themal conductors. The metals are generally good conductors of heat (thermal energy).
They are called good thermal conductors.
Non metals :P
conductors
They are good conductors of electricity because the outer electrons in each atom can easily come and go called a free flow of electrons.
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Metals are good conductors of heat. Plastics and wood are very poor.
Metals are good conductors. Some non-metals are good conductors, but many others are not.
