What are alloys? Give two examples.

Alloys can be defined as  mixtures of metals in definite ratio for most parts i.e. homogeneous in characteristic;some non-metals may also be present in minor quantities in certain kind of alloys.For formation of alloys,metal is initially melted and then other metals and/or metals are added depending on composition.

Two examples are enumerated as follows:

i)Bronze-containing 80%Cu and around 20% Sn, though small amounts of some other metals and non-metals are also present.

ii)Brass-Cu and Zn.

Hence,alloys are mixtures of multiple metals and few non-metals in definite ratio for most parts.

Examples include brass and bronze.
