Doped Tungsten Wire Comparison

Doped tungsten wire lengthy production processes, including tungsten metallurgy, powder metallurgy and metal forming system of billet main stage.

Advantages of doped tungsten wires

W31: W31 wires are standard doped tungsten wires with excellent non-sagging properties.

W91: W91 wires are non-sagging wires developed for higher-temperature use than W31 wires. They are suitable for halogen lamp filaments. Doped tungsten wire has higher non-sagging properties by maintaining inter-granular strength and suppressing void production at elevated temperatures by reducing the impurities content using our own technology.

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.

Doped Tungsten Wire-Fio de tungstênio dopado

Doped tungsten wire is very similar to non-sag tungsten wire. Non-sag tungsten wire is one of doped tungsten wires. Non-sag tungsten wire is doped K+, and there have been lots of other doped tungsten wire, such as Ca doped, Re doped, etc. Doped tungsten wire is manufactured in order for the wires need to get the properties of non-sag, tensity, ductility etc. 

More information, please contact sales@chinatungsten.com.

Fio de tungstênio dopado é muito semelhante ao fio de tungstênio não-sag. Fio de tungstênio não-sag é um dos fios de tungstênio dopados. Fio de tungstênio não-sag é dopada K +, e tem havido muita outro fio de tungstênio dopado, tais como Ca dopados, Re dopado, etc. fio de tungstênio Doped é fabricado a fim de que os fios precisam para obter as propriedades de não-sag, intensidade, ductilidade etc.
