Tungsten has the lowest coefficient of thermal expansion of any pure metal. The names tungsten and wolfram have been used for the metal since its discovery, though everywhere jön jacob berzelius ’s symbol w prevails. 但因為 tungsten 在瑞典文中也是白鎢礦的名稱，為了避免混淆，瑞典採用 volfram 作為元素的名稱。 在歐洲其他國家，主要以 德文 及各 斯拉夫語 為代表，則使用德語： wolfram 或 volfram，.

The low thermal expansion and high melting point and tensile strength of tungsten originate from strong. 原料 用於生產tungsten的原料有白鎢tungsten scheelite 和黑鎢tungsten concentrate. Tungsten is a premier journal dedicated to the science and technology of tungsten and related metals, including molybdenum, cobalt, vanadium, tantalum, niobium, rhenium, zirconium,.
Tungsten has the highest melting point and lowest vapour pressure of all metals, and at temperatures over 1650°c has.
The resistance of tungsten wire at room temperature is two times higher than that of aluminum wire, and three times higher than that of copper. Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them.
