Why are alloys, but not sure metals from which they are made,commonly used in electrical devices?

because alloy are stronger ( have high melting point) than pure metals. so alloy's wire doesn't break

Alloys unlike metals meet the requirements of high mp & resistivity, when you create alloys form metals you form certain bonds between the metal and the other substance you mix to make the alloy these newly formed bonds bind the alloy(turned from metal due to doping) together and don’t let it melt free at relatively higher temperatures then parent metal.
For the same reason, less free electrons( all thanks to newly formed bonds which hold elections captive in localized region) the conductivity falls down ( charge careers reduced ie less electrons are free to conduct the current).
This is the most satisfying answer among all the others.
