Brass does conduct electricity, but it is not a very good conductor. Not all metals conduct electricity to the same extent. Brass has a low electrical conductivity of only 28 percent, compared to metals such as silver and copper that have almost perfect electrical conductivity.
The conductivity of electricity through metals depends on the availability of free electrons in the atomic structure of the metal. Metals such as iron, copper, silver and aluminum have a greater number of free electrons that are mobile, which allows electricity to flow through them easily. Electricity flows only when electrons move in one direction through a metal.
Brass is an alloy of copper and zinc, but it does not have the same properties as either copper or zinc.
