    The melting point of a material is primarily related to bond strength. Materials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic weight, and electron structure--can also influence the melting point. Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals.
