Answer:- No alloys are not puely metals,as alloys are formed by the homogeneous mixture of two or more metals,so there must be a change in the physical or chemical properties of alloys.e.g; Copper(Cu) is a very good conductor of heat so it becomes hot instantaneously after geting heat from any outside source of heat but alloy brass (Cu+Zn) is not so good conductor of heat as compared to copper as it takes time to become hot.So,alloys are not completely we can say as metals.
