Tungsten Characteristics and Properties
Tungsten has several unique characteristics and properties that make it useful in various industrial and technological applications. Here are some of its key characteristics and properties:
High melting point: Tungsten has the highest melting point of all metals and the second-highest melting point of all elements after carbon. Its melting point is approximately 3,422°C (6,192°F), which makes it useful for high-temperature applications.
High density: Tungsten is a very dense metal, with a density of approximately 19.3 g/cm³. Its high density makes it useful for applications where weight is a critical factor, such as in aerospace and defense applications.
Hardness and durability: Tungsten is a very hard and durable metal, with a hardness of approximately 7.5 on the Mohs scale. Its hardness and durability make it useful in the production of cutting tools and other tools that require high wear resistance.
Resistance to corrosion: Tungsten is highly resistant to corrosion and oxidation, which makes it useful in applications where exposure to harsh environments or chemicals is a concern.
High thermal conductivity: Tungsten has a high thermal conductivity, which means that it is an excellent conductor of heat. This makes it useful in applications where heat dissipation is important.
High electrical conductivity: Tungsten has a high electrical conductivity, which makes it useful in electrical applications such as in the production of filaments for incandescent light bulbs and electrical contacts.
Brittle: Tungsten is a brittle metal and can break easily under certain conditions. This limits its use in some applications where toughness and ductility are important.
