Of all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure (at temperatures above 1,650 °C, 3,000 °F), and the highest tensile strength. Although carbon remains solid at higher temperatures than tungsten, carbon sublimes at atmospheric pressure instead of melting, so it has no melting point.
The melting point is also referred to as liquefaction point, solidus, or liquidus. Melting points of common materials Melting point of steel : 1425-1540 °C / 2600-2800 °F Melting point of gold : 1064 °C / 1947.5 °F Melting point of copper : 1084 °C / 1983 °F Melting point of iron : 1538 °C / 2800 °F Melting point of lead : 327.5 °C / 621 °F Melting point of silver : 961 °C / 1761 °F
The melting point is the highest temperature at which crystallization may occur.; It is also a temperature at which a solid (crystal) turns into a liquid. We say that such a body melts.; The melting point is specific for a given substance.For example, the melting point of ice (frozen water) is 0 °C.

30-07-2015· July 30, 2015. Source: ASM International. Computations show that a material made with just the right amounts of hafnium, nitrogen, and carbon would have a melting point of more than 4400 K (7460°F). That's about two-thirds the temperature at the surface of the sun and 200 K higher than the highest melting point ever recorded experimentally.
Metal with High Melting Point – Top 2. Rhenium (Re) Rhenium is a silver-white metal with the second highest melting point (3180 °C) after tungsten and has the highest boiling point. Commercial rhenium is generally powdered and can be pressed or sintered into a high-density solid in vacuum or hydrogen, with a density of more than 90% of the metal state.
Tungsten is the metal with the highest melting point. It is also relatively cheap, so there isn't really an argument to use "cheaper" metal with a slightly lower melting point.
12-08-2014· Glass transition temperatures are kind of like melting points, but some materials have a glass transition temperature and a melting point. Some initial casting about on the internet finds that rhenium and tungsten have melting points at about 3400 °C, and hafnium carbide claims to be 'one of the highest' at 4100 kelvin.
