Starck Tungsten Powders Not only does tungsten have the highest melting point (3,422 °C) and the lowest thermal expansion of any metal, it also has a high density (19.3 g/cm³), very high mechanical stiffness, and a very low vapor pressure. Thanks to these and other outstanding properties, tungsten metal is irreplaceable in many key industries. Characteristics of tungsten metal Tungsten heavy metal alloys exploit the metal’s high density, mechanical damping properties, high absorption capacity for ionising radiation, and easy machining characteristics. These alloys are used as mass-balance weights and damping elements in aircraft construction, in engines and power units, and as flywheel masses and centrifugal weights in machinery and equipment construction. They are also used in medical technology to shield and focus ionising radiation in X-ray and measuring equipment. High thermal resistance and excellent thermal and good electrical conductivity make tungsten-copper alloys suitable for applications in high-performance electrical switching contacts, such as heat sinks in the electrical industry, or for use as discharge electrodes. What’s more, pure tungsten metal is also used in the coating industry as a crucible material and a sputter target, as well as in high-temperature furnaces in the form of heating elements and heat shields. H.C. Starck Tungsten Powders manufactures tungsten metal powders through the reduction of tungsten oxides under an atmosphere of hydrogen.
