What are alloys? Write about them.

(N/A) Alloys are homogeneous solid solutions of two or more metals or a metal and a non-metal.
In alloys,the atoms of one metal are randomly distributed in the lattice of another metal.
Alloys are prepared by melting the components together. The general conditions for the formation of alloys are:
$(i)$ The difference in the metallic radii of the atoms should be less than $15\%$.
$(ii)$ Transition metals have similar atomic radii and other characteristics,which makes it easy for them to form alloys.
Properties: Alloys are generally harder than their constituent metals and have higher melting points.
Examples: Ferrous alloys are the most common. Metals like $Cr, V, W, Mo,$ and $Mn$ are used to produce various types of steel and stainless steel. Alloys can also be formed between transition metals and non-transition metals.
Examples include $(i)$ Brass $(Copper-Zinc)$ and $(ii)$ Bronze $(Copper-Tin)$. These alloys have significant industrial importance.
