Purpose of Making Alloys. From Structure, Properties, and Applications of Various Alloys. Purpose of Making Alloys. Pure metals possess few important physical and metallic properties, such as melting point, boiling point, density, specific gravity, high malleability, ductility, and heat and electrical conductivity. These properties can be modified and enhanced by alloying it with some other metal or nonmetal, according to the need.
the addition of alloying elements to metal melts to impart specific physical, chemical, or mechanical properties to the alloys. Alloying was used even in antiquity (this fact is attested to by the study of silent weapons discovered in archaeological digs).
