All About Tungsten in TIG Welding: Types, Selection and Use
In the early days of TIG welding there were only two types of tungsten that were commonly used. Pure tungsten was favored for aluminum and magnesium, and 2% thoriated tungsten was used for everything else. While these worked well for generations, research and development led to a broad range of tungsten electrodes, each with …

Chemistry of Tungsten
Most German chemists still refer to the element as Wolfram (wolf's metal). Pure tungsten was eventually isolated in 1783 by brothers Juan and Fausto Elhuyar. Tungsten is known chiefly as the metal in incandescent light bulb filaments (tungsten has the highest melting point of any metal).
Tungsten
Tungsten is a metallic transition element in Period 6, Group 6 of the Periodic Table. It was first described in 1783 by Spanish brothers Juan Jose and Fausto de Elhuyar. They named the element Wolfram after a term used by the ancient tin miners in Saxony-Bohemia, describing a still unknown mineral. The name was later changed to ...
Tungsten
Tungsten and its alloys are widely used for filaments in electric bulbs and electronic tubes. Tungsten carbide is of great importance to the metal-working, mining, and petroleum industries. Tungsten oxides are used in ceramic glazes and calcium/magnesium tungstates are used widely in fluorescent lighting.
Tungsten
Tungsten is a chemical element with atomic number 74 which means there are 74 protons and 74 electrons in the atomic structure. The chemical symbol for Tungsten is W. Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. Tungsten is an intrinsically brittle and hard material, making it difficult to work.
