What are Alloys?
Alloys are mixtures of two or more metals or a metal and a non-metal and cannot be separated into their components by physical methods. But still, an alloy is considered as a mixture because it shows the properties of its constituents and can have variable composition. For example, Brass is a mixture of approximately 30% zinc and 70% copper.
