2. Tungsten applications
2.1 Products for industrial applications
These are essentially :
tungsten metal ;
tungsten alloys: solid solutions, doped tungsten, dispersion-strengthened tungsten, heavy metal; pseudo-alloys ;
cemented carbides.
As tungsten metal is the most refractory of all metals, consolidation techniques using arc melting or electron beams are relatively recent...

Organization
International Tungsten Industry Association (ITIA)
ITIA was formally inaugurated in Brussels in February 1988 and registered as a scientific association under Belgian law. Some 60 companies (mining companies, producers, consumers, trading companies) from 19 countries are members of the association. It is extremely useful in distributing and exchanging valuable information on tungsten between the various groups and...
