we have advanced equipment and could produce tungsten screws of different specifications and shapes. Tungsten screw is also called tungsten heater. It is a metal composed of single-atrand or mulitiple-strand doped tungsten wires of different shapes.Because of its good corrosion resistance, high-temperature performance, stability and long using life, it is widely applied in mirror industry, kinescope industry, vacuum plating, metal vaporization and other fields.BTMMF has a long history in producing tungsten screw with the capacity and technology ranking the first class inside the industry.
