You can use ordinary tungsten to mark
lightbulbs?
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
Tungsten is not considered bulletproof on its own. While tungsten is a dense and hard metal, bullets can still penetrate tungsten depending on the caliber, velocity, and distance of the shot. Bulletproof materials typically include ceramic plates, steel, or composite materials designed to withstand ballistic impact.
The hardness and heat resistance of tungsten can contribute to useful alloys. Tungsten's high melting point makes tungsten a good material for applications like submarine ballistics. Tungsten alloys are used in a wide range of applications, including the aerospace and automotive industries and radiation shielding.Superalloys containing tungsten, such as Hastelloy are used in turbine blades and resistants. Tungsten's heat resistance makes it useful in composite applications as can be a highly-conductive metal to withstand the high temperatures.

A tungsten FC ring is likely a typo or confusion with tungsten carbide rings. Tungsten carbide rings are popular for their durability, scratch resistance, and affordable price compared to other fine metals like gold or platinum. They are a popular choice for wedding bands or fashion rings.
There are many uses for tungsten: Incandescent light bulbs: It makes up the filament of the bulb. It is used in the bulb because it can withstand extreme temperatures. Jewelry: The high scratch resistance and dark shine of tungsten makes it a very popular choice among men for rings and bracelets. Abrasive Coating: Many tools subject to cutting hard metals in harsh conditions are coated with tungsten. The high melting point and hardness of tungsten make it a valuable asset to machinery and cutting tools.
A math teacher is the job that uses prime and composite numbers.
Public key encryption is based on composite numbers. In fact it is based on composite numbers which are the product of two very large prime numbers.
Composite demand is a demand for a good that has many uses. An example is oil it is demanded as a fuel.
Tungsten is a chemical element with symbol W and an atomic number of 74. It is mainly used in making electric light filaments. It is also a major component in cemented carbides and high speed steels.
TIG welding uses tungsten electrodes. Some electrodes also contain Thorium some also contain Zirconiun some are pure Tungsten. Each has its own applications.
