Tungsten
You can find tungsten at work whenever the heat's on. Because no other metal can compare with tungsten when it comes to heat resistance. Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Tungsten is practically indestructible. For example, we use this material to manufacture high-temperature furnace components, lamp components and components for use in the fields of medical and thin-film technology.
