Electrical conductivity is the ability of a material to allow electricity to flow through it. This can be determined by measuring the voltage drop between a known current and a known length of cross section area.

Tungsten carbide is an alloy that combines tungsten and carbon. It is a good choice for industrial applications due to its strength, toughness, and hardness.

Physical properties

Tungsten has a unique structure with a hexagonal lattice. It also has half-filled 5d electron shells, which are able to create a magnetic dipole moment when exposed to an external field. This makes it very useful for magnetic applications, like magnets and switches.

Microstructural composition

Tungsten atoms are packed tightly in a dense matrix, with carbon atoms filling the interstices. This structure has a normal trigonal prismatic coordination, which allows tungsten to form a high temperature alloy called tungsten carbide.

Tungsten has a low thermal expansion capacity, which means that it does not melt easily. This property has led to it being used as a filament in electric bulbs, where it can heat up to incandescence without melting. It also has a high resistance to dissipation of electricity, so it is a good choice for power-consuming electronic components.
