Tungsten is a metal with unique properties making it an essential component in many industrial applications. Critical properties include - very high melting point, very high density, hardness close to diamond, thermally and chemically stable, excellent conductor, and environmentally benign.

The most important use is as tungsten carbide in hardmetals, used mainly for industrial drilling and cutting tools. Secondary uses are in electronics and specialist steels.

China accounts for over 85% of world tungsten mine production; western world supply is very limited.

USA, Europe and Japan consume ~55% of world tungsten, but produce only ~5%.

Chinese domestic demand has increased, and China has moved from a net exporter to net importer of tungsten concentrates. This increase in Chinese demand, combined with increased controls by the Chinese Government on their domestic tungsten industry and tungsten exports.

Concerns over security of supply of tungsten concentrates to western processors and industry end-users. This along with other factors have resulted in the EU categorising tungsten as a "critical raw material".

Chinese domestic consumption of tungsten is forecasted to grow by 5-8% annually between 2012 and 2016.

Growth markets for tungsten are still being identified, such as nickel-tungsten alloys that could replace chrome plating and nickel-tungsten alloys that could replace gold-nickel plating.

Tungsten, with essential applications in industry, aerospace and military, is a strategic commodity.  Stockpiles exist in the US and Russia. China and Japan have also indicated that they intend to build stockpiles and there has been some discussion of the possible creation of a European stockpile.

You may have heard that a tungsten carbide ring is unbreakable. This would have some good and bad effects. Having a wedding ring that would never bend, crack, scratch, or get marred would be a benefit.

Tungsten carbide rings are not indestructible. In case of emergency, you can remove them with relative ease. Just don't drop your wedding band on a hard surface - any Tungsten Carbide wedding ring (no matter who makes it) is brittle. It will crack, chip or even shatter upon impact with a hard surface or object. It is also not a metal or even solid, as Wikipedia confirms.

Mott Corp says that its porous metal components and filters are available in a range of refractory metal alloys including zirconium, titanium, tungsten, molybdenum, and niobium.

Mott Corp can design porous components or entire filter assemblies using refractory metals to meet various flow control or filtration requirements, to meet tolerances and to a sub-micron particulate removal. 

Porous components in refractory metals have melting points from 2400°C to over 3400°C and thus can meet demanding filtration or flow control requirements. They are also refractory metals are electrically conductive and chemically inert and can be a suitable material of construction for many where higher operating temperatures are critical.

You may know a few things about tungsten bands. Undoubtedly, you have heard that tungsten carbide rings have become the metal of choice for grooms throughout the nation. One of the main reasons this is so is due to its toughness. They resist scratching much better than any other metal out there. Few substances can scratch it. Diamonds are one of them. What some may find odd or shocking is that tungsten rings are not indestructible. Tungsten carbide rings can break! If a tungsten ring is dropped on a hard surface, it can break or crack.
