No, pencil leads are made up of graphite. Graphite has a macromolecular structure whereby each carbon atom is covalently bonded to 3 other carbon atoms in layers. Because of these strong covalent bonds, a lot of energy is needed to break these bonds, resulting in a high melting point. However, there are weak intermolecular forces between the carbon layers. Hence, little energy is required to separate them. This is why pencil leads are soft.
