The properties of graphite-density and mechanical properties Density: Crystallographically perfect graphite has a density of 2.265 g/cm3. Density can give a measure of crystal perfection and in practice, synthetic graphite rarely exhibits a density above 2.0 g/cm3 with some versions as low as 1.6 g/cm3.

Excellent mechanical properties of copper

2019/11/1Copper is the best choice as a metal matrix due to its excellent properties such as higher thermal and electrical conductivity, cost-effective but has poor mechanical properties [2,3]. To improve the properties of Cu matrix different kinds of filler are used such as CNTs [ 4 ], graphite [ 5, 6 ] and graphene oxide [ [7], [8], [9] ].
