Conductors include almost all metals, as well as aqueous solutions that have ionized solutes (such as salt in water). Other solutions may be poor conductors. Non-conductors include air, wood (mostly cellulose), rubber, plastic, and many minerals.
Insulator materials will not carry or conduct electricity.
"Conductivity Countdown: Investigating Materials for Electricity Flow"
Materials that do not conduct electricity are called insulators. Examples include rubber, plastic, glass, and ceramic. Insulators have high resistance to the flow of electricity due to the lack of free-flowing electrons.
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
copper, metals...
Usually, yes.
Materials that do not conduct electricity well are Insulating materials, or insulators. Examples include glass, rubber, plastic, air, ceramic, porcelain, dry paper and dry wood. Pure water will not conduct electricity at all.
For a material to conduct electricity , it has to be impure , so for example pure silicon cannot conduct electricity but Silicon chips in computers that are mixed with other things can. So the materials that conduct are charged with little particles that allow the flow of electricityBecause of electrolytes. Or because of the metal something is made of.
Materials that conduct electricity well include metals such as copper, aluminum, and silver. In contrast, insulating materials like rubber, plastic, and glass do not conduct electricity. Some fabrics that can conduct electricity are conductive fabrics made by weaving metal threads with conventional fibers.

Superconducters are materials that conduct electricity with little or no resistance.
