Application of tungsten alloy in electronic industry
Tungsten and its alloys are widely used in electronics and electric light source industry. The electron tube heater of the lamps used to manufacture all kinds of lighting is used the doped tungsten wire with sag resistance. Adding rhenium to the doped tungsten wire, the thermocouple which is manufactured by the tungsten rhenium alloy wire with low rhenium content and the tungsten rhenium alloy wire with high rhenium content has a extremely wide temperature-measuring range（0~2500 ℃).The linear relationship between temperature and thermal electromotive force is very well, the temperature response speed (3 sec) is very quickly, and the price is relatively cheap. So it's the ideal thermocouple measured in the hydrogen atmosphere.
Tungsten used its high melting point under the premise without the loss of the mechanical integrity becomes a kind of thermionic emitter. For example, it can be used for the electron source of the scanning electron microscope and transmission electron microscope. And it also used for the filament of X ray tube. In X - ray tubes, electronic wire has been accelerated, the collision of tungsten and tungsten rhenium alloy anode, and then emit X rays from the anode. In order to produce X ray，the tungsten wire is asked for the high production of the electron beam energy. So the spot on the surface crashed by the electron beams is very hot. So the rotating anode used in most of the X ray tube, large size of the tungsten wire is also used as a heating element of vacuum furnace.
Luoyang Sansui metal materials Co. Ltd. focuses on manufacturing all kinds of tungsten, molybdenum, titanium, tantalum, niobium, zirconium and nickel and other products. Shapes are divided into rod, plate, wire and crucible etc., and it can produce some special parts according to customers' demand. Our products have many advantages, such as high melting point, high strength and good electrical conductivity, thermal conductivity, small coefficient of expansion and corrosion resistance. Our products have been widely used in military industry, electronic industry, aerospace and electric light machinery industry etc..The best-selling products in more than 20 provinces and cities, are exported to Japan, Southeast Asia, Germany, France, Taiwan and other countries and regions, and obtained from the customers' good praise and trust all over the world's.
