Alloys are useful (if this is what the question is getting at) because mixing elements of the periodic table alters their colligative properties.
i.e. mixing two metals could change substance's melting point, allowing it to more easily resist high temperatures. Also, mixing metals can change the way they bind together, and create an altogether stronger material than you can find using any single metal alone.They can improve a metal's properties

All chemical bonds, including those found in network solids,
derive from the electromagnetic force. Positively charged protons
attract negatively charged electrons. Although atoms start off with
an equal number of protons and electrons, and are therefore
electrically neutral, the electrons rearrange themselves in ways
that create attractions between atoms. Covalent bonds
