1 Diamond is an excellent electrical insulator, Graphite is a good conductor of electricity. 2  Diamond is the ultimate abrasive, Graphite is a very good lubricant. 3  Diamond is usually transparent, Graphite is opaque.  Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system.
It is due to the availablity of free electrons. All metals such as Copper can be considered as atomic nuclei surrounded by a sea of electrons which are free to move around â¦ with little resistance, which makes all metals good conductors of electricity (and heat, incidentally).he best conductors are silver, copper, gold and aluminum respectively. Cost, weight and ease of handling dictate using copper or aluminum as conductors in most industries. Also it is used in piping as it is unreactive with water.
