Tungsten is widely used as refractory metals. In wire form, tungsten wire is essential for the production of lighting products 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.
The important applications of tungsten 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 sizes of tungsten wire, 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 filament is arguably the key component of the incandescent lamp business.

Tungsten granule/pellet is the processiong of tungsten metal into small particles, also known as tungsten flux.
Apprearance of tungsten granule/pellet: bright gray polyhedron granule; -
Tungsten heater made of tungsten wire, features high melting point and high corrosion resistance, mainly applied for vacuum metallizing, such as aluminizing scope, chrome scope, mirrors, plastics and heaters elements for decoration articles.Tungsten heater can be stranded into single or multi wires according to the samples or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.2-1.2mm.
