6. Alloys
In 1981, tungsten consumption in market economy countries was 25,000 t, of which :
55% for the manufacture of cemented carbides ;
20% for tool steels, which will not be discussed here since tungsten is in the minority (see refractory steels and alloys
in this treatise);[M 325] 15% in the form of tungsten metal and alloys and, principally: heavy metal, infiltrated tungsten, doped tungsten, W-Re alloy; article Refractory steels and alloys
in the present treaty;[M 325] 10% for superalloys (which we won't go into here) and the preparation of certain compounds for electronics, calatyse,...
