Physical and Chemical Characteristics Tungsten wolfram is a transition metal distinguished by a suite of exceptional properties. The most visible example is the incandescent light bulb, where a thin filament of tungsten glows brightly when heated by an electric current.

3 times that of water, making it significantly heavier than lead. Even some jewelry utilizes tungsten carbide due to its extreme scratch resistance and metallic luster.
This powder is then sintered into ingots or fabricated into wires, rods, and other shapes through processes like powder metallurgy and powder injection molding. Tungsten, also known by its older name wolfram, is a chemical element with the symbol W and atomic number 74.

Consequently, the element bears the chemical symbol W, a legacy of its wolframite origins, while tungsten dominates as the common name in most contexts. Extraction and Production Process Commercially, tungsten is not found in pure form but is extracted from ore minerals such as wolframite and scheelite.
