important alloys and their composition and usages entranciology

 

Alloys are the metals made by combining two or more metallic elements in various compositions. These are formed to give greater strength and high resistance to corrosion like Stainless Steel, Brass etc. Below, we have given the information of some important alloys, their composition and usages.
