General Data > Metal Alloys

This page details some of the most common metal alloys. An alloy is a metal, blended with another metal or non-metal to give it special qualities such as resistance to corrosion, greater hardness, or tensile strength. The atoms in a metal are held together by the metallic bond. In a pure metal the atoms are all the same size and can slip over each other if a force is applied. In an alloy, the presence of different sized atoms can prevent such dislocations from weakening the metal.
