Nanoparticles exhibit unexpected behavior that cannot be achieved with basic elements in their original states. These unexpected properties of nanoparticles have expanded their applications to the field of cosmetics, biomedicine, electronics, etc. This article will look into the properties and applications of tungsten carbide-cobalt nanoalloy.
Tungsten carbide-cobalt is an alloy of hard, ceramic tungsten carbide and the ductile cobalt, often known as cemented carbide. The material is a metal matrix composite, in which cobalt particles are ambedded in a tungsten carbide matrix. The tungsten carbide can form as WC or WC2, depending on synthesis conditions. Cobalt content varies from around 1% to 30% by weight, depending on application.
Some of the noteworthy properties of this alloy are strength, hardness, high electrical and thermal conductivity and high malleability and ductility. Tungsten is a Block D, Period 6 element, cobalt is a Block D, Period 4 element and carbon is a Block P, Period 2 element. These particles are available in a variety of forms such as ingots, foils, sputtering targets and plates.
The chemical properties of tungsten carbide-cobalt nanoparticles are as per the table below.

European ammonium paratungstate prices(APT prices) unchanged, market silent.
Offering prices in the European ammonium paratungstate market(APT market) have held unchanged over the past two weeks, ranging between USD405-410mtu in warehouse Rotterdam as of Thursday.
However, the thinly traded European spot market is putting pressure on stockholders, especially as the slower summer months limited sales further, and as a result some sales have been concluded in the lower range of USD400-405mtu in warehouse Rotterdam.
