Producing tungsten wire is a complex and difficult process. The whole process must be strictly controlled by controlling the proper chemical composition to ensure the physical properties of the finished tungsten wire.

Coiled tungsten wire is undoubtedly the most critical part of producing incandescent lamps. The resistivity of tungsten filament is 5.3*10^-8.

Gold-plated tungsten wire definitionGold-plated tungsten wire means that the tungsten wire is coated with a layer of gold. Gold-plated tungsten-rhenium wire refers to tungsten-rhenium wire.

With the continuous maturity of high and new technologies such as plasma arc and laser, higher requirements are also placed on the properties of cerium tungsten wire. However, due to the difficulty in controlling the uniformity of cerium-tungsten doping and the difficulty in wire drawing.

In order to make up for the shortcomings of the existing doped tungsten wire with cooling, low thermal resistance and poor photoelectric performance, some researchers pointed out that the performance of tungsten wire can be improved by changing the addition method of lanthanum. The preparation ste

In order to further improve the strength, toughness and high temperature resistance of pure molybdenum wire, the researchers said that rare earth lanthanum and tungsten elements can be added to molybdenum wire.

The ultra-fine tungsten wire can be prepared by electrolytic corrosion method, wherein the ultra-fine tungsten wire with a diameter of less than 7 μm is the main raw material for preparing the load of the Z-pinch wire array.
