Future Rhenium Co., Ltd
Address：Zone A, Building 2, No. 581, Heilongjiang Road, Tianyuan District, Zhuzhou City, Hunan Province
Directly heated cathodes or heater coils for indirectly heated cathodes in cathode ray tubes for TV sets or computer displays, X-ray tubes, electron tubes, klystrons, magnetrons for microwave ovens.
Thoria or rare earth oxide alloyed electrodes for inert gas welding, as well as High Intensity Discharge (HID) lamps.
Tungsten disks for substrate of high power semiconductor rectifying devices; Electrical contacts.
High temperature furnace parts such as tungsten heating coils, reflectors and structural material.
Tungsten / tungsten-rhenium thermocouples for measuring the temperature in such furnaces.
X-ray tubes for medical use are not only equipped with a tungsten emitter coil, but also a static anode made of tungsten or tungsten-rhenium. Important here are not only the low vapor pressure, but also tungsten’s good heat conductivity and the wavelength of the resulting X-rays.
Modern business machines, such as photocopiers, facsimile machines, laser printers and air cleaners are equipped with tungsten charger wires. Not only drawn tungsten wire, but also electro-polished, gold-plated or platinum clad tungsten wires are used for this application.
Modern computer processors generate a heat output per square centimeter similar to that of a household cook top. Tungsten-copper heat sinks and the processor fan remove the heat.
