No, it is not.It is an element.Hence it is a pure substance.
Note: Alloys are Homogeneous mixtures which are formed only when two or more metals are mixed together.
Examples:- German Silver, Steel.
We should be strong as tungsten heavy alloy,tough as tungsten carbide.This is the motto of China Tungsten Online
This alloy is not known today.
tungsten is a very strong and brittle metal. there are no darts made from 100% tungsten. it is always made with an alloy as tungsten is very brittle. the alloys are usually nickel, zinc and brass.
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 used as an alloy in ballpoint pens that is nearly twice as dense as lead. The strong odor associated with tungsten is a result of its highly toxic oxide, tungsten oxide.
Tungsten steel does not have a specific melting point, as it is an alloy mixture of tungsten and other metals such as carbon or nickel. However, pure tungsten has a melting point of 3422°C (6192°F), making it one of the metals with the highest melting points.
Mixing rhenium into tungsten improves its high-temperature strength and resistance to wear and corrosion. This alloy is commonly used in aerospace and defense applications where these properties are critical for performance.
An alloy for electrodes containing only 1-2 % thorium has a greater melting point.
Heat it to a temperature somewhat above 3,400 degrees Kelvin.
Several are used, but Nickel is the primary additive. Others include (among MANY others) are Tungsten, Molybdenum, etc., depending upon the desired properties of the final alloy .
Tungsten (pronounced /tʌŋstən/), also known as wolfram (/wlfrəm/), is a chemical element with the chemical symbol W and atomic number 74. Tungsten is one of the heaviest materials after gold, for the density of tungsten is 19.25  g•cm3(near r.t.).Tungsten is one of the Nonferrous Metals, and also it is as molybdenum and rare earths which are Refractory Metals.It is also used in eletrical bulbs as filament.
Tungsten carbide is commonly used as an alloy in ballpoint pen tips due to its durability and wear resistance. It helps ensure a smooth writing experience and extends the lifespan of the pen.
