Tungsten's high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris submarine-launched ballistic missile. [82] Tungsten alloys are used in a wide range of applications, including the aerospace and automotive industries and radiation shielding. [ 83 ]
Tungsten's high density and strength are also key properties for its use in weapon projectiles, for example as an alternative to depleted Uranium for tank gun rounds. [23] Its high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris. [24] Some of the applications of tungsten are ...
The Spark Erosion (EDM) process calls for copper tungsten. Usually, this process is used with graphite, but as tungsten has a high melting point (3420 °C) this allows the CuW electrodes to have a longer service life than the graphite electrodes. This is crucial when the electrodes have been processed with complex machining.
Tungsten carbide (chemical formula: W C) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The tantalum–tungsten alloys are characterized by their high melting point and the tension resistance. The properties of the final alloy are a combination of properties from the two elements: tungsten, the element with the highest melting point in the periodic table, and tantalum which has high corrosion resistance.

The elements in the group, like those of groups 7–11, have high melting points, and form volatile compounds in higher oxidation states. All the elements of the group are relatively nonreactive metals with a high melting points (1907 °C, 2477 °C, 3422 °C); that of tungsten is the highest of all metals.
Because of its high melting point, ferrotungsten is a robust alloy with applications in aerospace [3] and making of tungsten-containing steel. Tungsten's unique electrical capabilities has made ferrotungsten useful electron microscopes and in IC chips.
