Doped Tungsten Wire

Doping in blue tungsten oxide or tungsten oxide mixed with trace K2O, Al2O. And SiO2. Doped tungsten wire, performance is better than ordinary tungsten wire, widely used in microwave ovens, television , welding materials, special lighting.

Adding tungsten rhenium can significantly improve the ductility (plastic ) and recrystallization temperature. Some tungsten rhenium alloy after appropriate annealing treatment, the extension rate of 5% , much higher than pure tungsten higher. Adding Tungsten thorium oxide (ThO2) the formation of tungsten thorium alloy with high thermal electron emission ability, can be used as hot cathode tube, welding electrodes, but the long-term radioactive ThO2 not been resolved.
