The electrical properties of Bulk metallic glasses (BMGs) were reviewed. It was found that the change in temperature coefficient of resistance (TCR) of BMGs, shows three different behaviors against increasing temperature. It is also observed that micro alloying can change TCR from positive to negative values (conductor to semi-conductor). Also it was revealed that, BMGs have a wide range of electrical resistance from near-zero up to high values. Finally, the applications of electrical resistance in determining the characteristic temperatures and glass forming ability (GFA) were reviewed and found that electrical resistance is an important parameter in determining the mentioned parameters.
