Tungsten Products

Tungsten, also known as wolfram, is a lustrous, silvery-white metal that tarnishes in air. Tungsten has the highest melting point of all other non-alloyed metals; it also has the highest tensile strength. Pure tungsten is ductile; however, impure tungsten is often brittle and hard making it difficult to work with. Tungsten is one of the five major refractory metals, meaning that it is has a very high resistance to heat and water.

Among worldwide tungsten suppliers, HMME is trusty. Various Specification:s and shapes of tungsten special part can be produced according to the requests of customers: tungsten metal powder, tungsten carbide, tungsten steel and other tungsten compounds. Tungsten, also known as wolfram in German, is a chemical element with atomic number 74. The chemical symbol for tungsten is W which stands for wolfram. The name "tungsten" means "heavy stone" in Swedish. Tungsten is a grayish-white lustrous metal in raw form. It is often brittle and hard to work, but, if pure, it can be worked easily.

Due to its hardness, tungsten is used in of heavy metal alloys; it is also used in military applications, and can be found in penetrating projectiles. A significant amount of tungsten, approximately 18%, is used in making high speed steel (steel that can cut through materials at higher speeds than carbon steel). Tungsten carbide, due to its hardness, makes it a key component in tools. Tungsten’s high melting point lends its properties to the aerospace industry for high-temperature applications such as electrical, heating and welding applications. Tungsten is also used in jewelry due to its wear resistance.

Pure tungsten is used mainly in electrical applications, while tungsten compounds and alloys are used in various applications, most commonly in incandescent light bulb filaments, X-ray tubes (as both the filament and target), and superalloys.
