Dumet wire bonded to Swedish Iron tips I presume!

Manufactured articles should be made to be used, not made to be sold!

No, W it is not, it is stainless nickel-chromium steel

Usually electrodes of negative glow lamps, are made from iron and not tungsten.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

What is the choice of the material based on ? I'd only think about work function, but that of Fe is pretty average among other metals

Swedish iron is very pure malleable iron with a low carbon and occluded gas content. It was originally perfected in Sweden using an age-refined pyrometallurgical reduction process. It is often used for cathode glow lamp electrodes because its sputter (evaporation and deposition on the bulb as blackness or mirroring) rate is low.
Interesting that it is one of the nickel chromium stainless grades though. These are very tough materials mechanically with enormous tensile strength. Somenody has discovered that they must possess a low sputter rate too.
Stainless steel (not sure which actual alloy, as there are now many) was discovered by accident at an armament works where different steel alloys were being tried for use to fabricate rifle barrels. All the "dud" tested barrels were tossed out into a yard, in the rain. After some time, most had gone rusty, but a few hadn't and they (and more recently developed similar alloys) are the alloys we now call stainless steels. Most stainless alloys are alloys of a large quantity of iron with smaller amounts of usually chromium and nickel added but some use vanadium too. One odd property of both nickel and nickel containing alloys is their low heat conductivity. Ever noticed how if you hold a stainless steel pole on the bus or train on a cold day, that your hand rapidly heats up that section of the pole it is holding, whereas if you did the same with a copper pipe or aluminium pole it would act as a heatsink and freeze the palm of your hand!
