Theresistivity of an alloy is higher than thepuremetal. Moreover, at high temperatures, the alloys do not meltreadily. Hence, the coils of heating appliances such as electrictoasters and electric irons are made of an alloy rather than a puremetal.

If there is an electric appliance then it will cause energy loss due to heating so most of the natural elements that exists does not have resistance to corrosion due to heating effect. So to have more durability of heating parts they will be given added resistance by making them into alloys. While metals get melt down or gradually soften die to overheating, alloys having higher melting point will be more durable and thus will be of less maintenance.
