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 ]
Gas tungsten arc welding (GTAW, also known as tungsten inert gas (TIG) welding) equipment uses a permanent, non-melting electrode. The high melting point and the wear resistance against the electric arc makes tungsten a suitable material for the electrode. [21] [22] Tungsten's high density and strength are also key properties for its use in ...
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.
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.
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.

Ferrotungsten is relatively expensive, with the prices around $31–44 per kilogram of contained tungsten. [4] During World War 2, over 21,000,000 lb of Ferro-tungsten and other ferroalloys were shipped to Russia on lend-lease. [3] The cost was more than $12,000,000. Ferrotungsten comes from rich ore raw materials primarily of wolframite or ...
Tungsten carbide (chemical formula: WC) 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 ...
Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...
