Alloys are homogenous mixture because:
(i) It shows the properties of its constituents materials
(ii) It has variable composition, for example, brass is considered a mixture because it shows the properties of its constituents – copper and zinc. Also, it has a variable composition (amount of zinc in brass can vary from 20 to 35 per cent).
(iii) The elements that make up the mixture are only physically together and not chemically bonded.
