one of the criteria for a question is-
Compare and contrast theoretical material properties of metal and non-metals with practical test data.
my materials are copper and graphite, i am struggling to find any relevant test data.
the question is about ductility and why copper is used for wiring and graphite is not. now the answer is straight forward i have done the write up, however finding any graphs or charts to back up my answers is proving difficult.
i have seen that copper has a 117GPa young's modulus
and graphite has 4.1 GPa young's modulus
my book states the lower the young's modulus the more ductile something is but i know that graphite is brittle and not ductile.
any links to information for both copper and graphite ductility would be most useful.
thanks in advance
