Is a brass key a conductor or insulator?
It is
highly conductive
which is why it is has been used in electrical wiring since the days of the telegraph. Brass however – which contains copper – is far less conductive because it is made up of additional materials that lower its conductivity, making it unsuitable for electrical purposes.

What are the 10 example of insulator?
Conductors are
materials that permit electrons to flow freely from particle to particle
. … Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
Which metal is the best conductor of electricity?

- Aluminum.
What is a good insulator?
Plastic, rubber, wood, and ceramics
are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.
What is the strongest conductor?
