Tungsten scrap is a very valuable raw material due to its high tungsten content in comparison to ore. Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores.
Tungsten heavy alloys (WHAs) belong to a group of two-phase composites, based on W-Ni-Cu and W-Ni-Fe alloys. Due to their combinations of high density, strength, and ductility, WHAs are used as radiation shields, vibration dampers, kinetic energy penetrators and heavy-duty electrical contacts. This paper presents recent progresses in processing, microstructure, and mechanical properties of WHAs.
In a first processing step tungsten is extracted from the raw materials into a solution, then cleaned and finally precipitated into a pure intermediate product, ammonium paratungstate (APT). With our state-of-the art technologies we produce high-end tungsten oxide, tungsten metal and tungsten carbide powders for the powder metallurgical industry.
