I need some help with my science fair project question and I want to know what metal it is honestly it has to be copper write that is what wires are made of?

Actually aluminum is not illegal in the USA. Certainly not as a blanket statement.anorlunda said:Aluminum is cheaper than copper and conducts well, but it is illegal in house wiring in USA building codes.
Edit: Carbon conducts very well, but cheap forms of carbon don't bend well.
Everything has advantages and disadvantages.

A conductor is a material that allows for the flow of electricity or heat. It is usually a metal or a material with high electrical conductivity.
A material is considered a good conductor if it has a high number of free electrons that can easily move in response to an electric field or thermal energy. This allows for the efficient transfer of electricity or heat through the material.
The atomic structure of a material plays a crucial role in its conductivity. Materials with a simple atomic structure, such as metals, tend to have a high number of free electrons, making them good conductors. On the other hand, materials with a more complex atomic structure, like ceramics, have fewer free electrons and are poor conductors.
Yes, the temperature of a material can affect its conductivity. As the temperature increases, the atoms in the material gain more thermal energy, causing them to vibrate and collide with each other. This disrupts the flow of electrons, decreasing the material's conductivity.
Aside from atomic structure and temperature, other factors such as impurities, crystal structure, and the presence of magnetic fields can also affect a material's conductivity. These factors can either increase or decrease a material's ability to conduct electricity or heat.
