Simply put, metals with the highest melting points belong to a category called 'refractory metals'. These metals have stronger electrostatic forces holding the atoms together due to covalent bonding formed by the electrons in their d orbitals, hence more energy is required to break the bonding in order to melt the metals. read more
Although many metals have high melting points, there is a select group of a few elements that have exceptionally high melting points and are physically strong. These are refractory metals, or metals with a melting point of at least 2,000 degrees Celsius, or 3,632 degrees Fahrenheit. read more
