Tungsten Heavy Metal Wire

Tungsten heavy metal has the highest melting point (3410°C or 6170°F) of all metals.  The extremely high melting point of pure tungsten makes all the common manufacturing techniques used for metals such as iron impractical. Specialized methods make possible the processing of pure tungsten into rod, sheet, and wire for a wide variety of high temperature applications including incandescent lamp wire, TIG welding electrodes, and high temperature heat shielding.

Tungsten heavy metal wire is made of the tungsten powder whose purity is 99.95%. It has a good high-temperature tensile strength and corrosion resistance after sintering, forging, and drawing

The process of making tungsten heavy metal wire is complex and difficult. The process must be tightly controlled in order to insure the proper chemical as well as the proper physical properties of the finished wire. Products we have manufactured are always at the highest standards and will perform consistently well.

The important applications of tungsten heavy metal wires are for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and evaporation sources in metalizing processes. Thicker wire sizes, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal, lead parts in the lighting and electronic industries.
