<h2>Answer:</h2>
A pure metal has specific properties. Sometimes we need that metal but with modified properties. So for the modification of properties we make alloys.
<h3>Explanation;</h3>
- An alloy is a mixture of two elements, one of which is a metal.
- Alloys often have properties that are different to the metals they contain.
- This makes them more useful than the pure metals alone.
- For example, alloys are often harder than the metal they contain.
