It is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be disigned by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3, BeO),Semiconductors (Si),Metals (Kovar), etc. The products are widely applicated in the fields such as radio frequency,microwave,high power diode packaging and optical communication system.

The main Features of our tungsten filament include: high melting point, high resistance, good intensity , low evaporation pressure and long service life.

Tungsten wire uses high purity 99.95 top grade Tungsten powder as raw materials to ensure high hardness and tensile strength work performance. We use introduced equipment to inspect quality when product finished.

They were widely used in the manufacture of special electric light sources, electric vacuum, various heating components, medical equipment, and cut resistant gloves.
