Tungsten material Tungsten material Tungsten material

Tungsten is the most widely used of the refractory metals. In wire form, it is essential for the production of lighting products such as wire filament, and other goods where its high temperature properties are of use. Among its properties are a melting point of 3410°C, a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, along with good electrical and thermal conductivity.

Tungsten wire / Tungsten heater

Important applications of this metal wire 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 metallizing 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.

Tungsten rod / Tungsten bar

Tungsten rod / Tungsten bar can be widely used in illumination, heater and the electronic mechanical engineering, etc. And also can be used in making the electricity photo source, the automobile and the tractor light bulb, make lattice side rod, framework and contact materials and so on.

Tungsten Electrode

Tungsten electrode product is the traditional and advantages product in our factory. While unceasingly optimizes the cerium tungsten, the thorium tungsten, the pure tungsten and so on ordinary electrode production craft, our factory centralized scientific research strength, successively researches and develops the lanthanum tungsten electrode, zirconium tungsten electrode, yttrium tungsten electrode and so on, receives the market widespread welcome. Proprietary-Compound Tungsten electrode is successfully developed, which has creating a model of cooperation among enterprises.

Tungsten Sputtering Target

Tungsten sputtering target is a new type of Physical Vapor Deposition (PVD) method. Sputtering is widely used in: flat panel displays, glass industry (include architectural glass, automotive glass, and optical film glass), solar cells, surface engineering, recording media, microelectronics, automotive lights and decorative coating, etc.
