What are the substances in tungsten?
There are none, tungsten is a pure element so it is made of only tungsten.
Is tungsten a pure substance or mixture?
Tungsten, like many other metals is found in ore. Often time in both an oxidized and in elemental form
How do you identify Tungsten?
Tungsten is heavy and fragile . Pure tungsten metal should be in dark grey color, tungsten metal usually use in industrial for filament and making steel. Another important part for tungsten is the tungsten carbide, usually use in jewelry. Tungsten carbide jewelry are in bright silver color, it's made from the 85.7 tungsten carbide and together mixed titanium.
What is tungsten hardness?
According to several publications Tungsten Carbide measures a 9 on the Mohs Hardness Scale. A Diamond measures 10 on the Mohs Hardness Scale meaning it would require a diamond to scratch Tungsten Carbide. Tungsten has an official hardness on the Mohs Hardness Scale of 9, but can be as hard as 9.5 on the Mohs Hardness Scale making it almost scratch proof. Now if you are talking about pure Tungsten the hardness is only 7.5 on the Mohs Hardness Scale making it softer than Sapphire, Ruby, Emerald, Alexandrite, Topaz and Spinel. When Tungsten is compounded into Tungsten Carbide the hardness rises greatly sometimes almost equaling the hardness of Diamonds. Tungsten Carbide is five times harder than 316L Surgical Grade Stainless Steel.
Is lead a pure substance?
Lead is an element so it is a pure substance.
What are the substances in tungsten?

What is the pure metal?
Tungsten is the strongest pure metal in the world. Tungsten has a very high density, more than 19.3 times denser than water. It is denser than uranium and lead.

What two metals are in the core?
Of the pure metals, tungsten and titanium are probably the strongest. Certainly tungsten heads the list as it has the highest tensile strength of all pure metals.
Is tungsten carbide and graphite the same element?
Technically no, since an element defines that it is a single atom. Tungsten Carbide is a chemical compound consisting of Tungsten and Carbon (W2C) and Graphite is a form of pure carbon
What metal has the highest melting temp?
Tungsten has the highest melting point of all metals
Highest melting point of any pure element?
Tungsten It melts at 3683 K
Is there a quality difference between tungsten and tungsten carbide?
Yes, there is a quality difference between tungsten and tungsten carbide. Tungsten carbide is a compound made by combining tungsten metal with carbon atoms. It is much harder and more durable than pure tungsten. Tungsten carbide is commonly used in various industries for its excellent strength and resistance to wear and corrosion.

How expensive the tungsten carbide?
As of Oct 2008, The price for pure metal is around $20,075 per tonne (Wikipedia).
Is tungsten a mixture a compound or an element?
Tungsten is an element. It has chemical symbol W. An element is a pure substance that cannot be further broken down into simpler substances through chemical means. A compound, on the other hand, is a substance that is composed of two or more elements that are chemically combined.
