Tungsten is a chemical element with the element symbol W and the atomic number 74. It is one of the transition metals, in the periodic table it is in the 6th subgroup (group 6) or chromium group. Tungsten is a high-density, shiny white heavy metal that becomes brittle even with very small amounts of contamination. It is the chemical element with the highest melting and boiling point. Its best-known use is therefore the filament in incandescent lamps.
Due to the high material value, the recycling of tungsten is of considerable economic importance. Technologically, a distinction is made between soft scrap and hard scrap. Soft tungsten scrap is grinding sludge, powder and chips from the processing of workpieces containing tungsten. Tungsten hard scrap, on the other hand, is pieces of hard metal, tungsten metal and tungsten alloys.
