I'm doing a science project and I don't get this question:What are the properties of copper wire compared to the properties of the graphite from a mechanical pencil?Please awnser it!
when it gets extruded it is usually cold worked which distorts the crystalline structure which makes it stiffer/harder. if you heat the metal the energy allows the crystalline to move about and return back to their natural un-distorted form. This makes the metal more maleable. The higher the temperature the easier it is to bend the metal.

You can figure out some properties just by looking at them. Copper is a shiny yellow metal while graphite is a dull black form of carbon. Copper is ductile, graphite is brittle. Actually, I believe pencil lead is not pure graphite, but has clay and binders added. Electrically, copper is a much better conductor, while graphite is a moderate conductor - better than things like wood but worse than metals. (regular fuse wire is not made of copper, or not pure copper. )
Copper is very good conductor of electricity as compared to graphite. 2 copper is used in fuses, while as graphite is not.
