Graphene is the strongest substance known to man. It is a single layer sheet of carbon atoms. All of these atoms are bound to form a hexagon lattice it is the thinnest substance known to man at only one atom thick. Although it is thin, it is 100 to 300 times stronger tan steel. Graphene is also the best and most efficient way to conduct electricity and heat when at room temperature. To put it in perspective on how strong it is, you would need an elephant balancing on a pencil point side facing the graphene to break it.

Engineers have studied this substance to confirm that it is the strongest in the world and is use in various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials.
