* Metallic Bonding: This type of bonding involves a "sea" of delocalized electrons shared by a lattice of positively charged metal ions. The electrons can move freely throughout the structure, giving metals their characteristic properties like conductivity, malleability, and ductility.

* Alloys: Alloys are mixtures of two or more metals (or sometimes a metal and a nonmetal). The atoms of the different elements are held together by the same metallic bonding that exists in pure metals. The presence of different types of atoms alters the properties of the alloy compared to the pure metals.

Examples:

* Bronze: An alloy of copper and tin.

* Brass: An alloy of copper and zinc.

* Steel: An alloy of iron and carbon.

Important Note: While metallic bonding is the primary type of bonding in alloys, there can be other types of bonding present depending on the specific alloy. For example, some alloys may have covalent bonding between specific atoms.
