this is because metals have low resistance to heat whereas the motive to make alloys is to provide higher resistance and strength..therefore Alloys are used to make heating devices so that they can resist high amount of heat..metals are used for making wires because they are good conductors and usally wires do not get very hot unless there is a short circuit..Thats all.
I hope this is what u are looking for and i think this will help u..

Dear Frnd,
here everything is the game is Resistance!
★ WHY METALS ARE USED TO MAKE WIRES/CABLE? -
Nearly all the Metals have less Resistivity. ie. they don't heat up fast. If they'll heat up, the wire will melt. And short circuit can happen. So Metals are used to make Wires/Cables.
Eg. Generally, wiring in our home and in devices are pure copper. So, whether it's phone chargers, or microphones, or our home wirings it's all still copper.
★ WHY ALLOYS ARE USED FOR MAKING HEATING DEVICES? -
Alloys have very high Resistivity. is. they heat up easily and quickly, So they are Generally used in making heating devices.
Eg.
> Nickel-chrome (nichrome) wire, like tungsten, can survive high temperatures, and the higher resistance is desirable. Being cheaper than tungsten, is used in heater wires, where the wire doesn't need to get white-hot.
> Solder, which is an alloy of tin and lead, or other mixes of metals in the case of lead-free solder, is used for bonding electrical components to copper pads on PCBs. The low melting temperature of tin-lead makes it suitable for this task.
> Cryogenic wire is often phosphor bronze (copper, tin, phosphorus), where the resistance of this alloy doesn't change much at very low temperatures.
Hope it cleared ur doubt
