Question

5. Enumerate advantages and disadvantages of alloys over pure metals

Answer 1

Explanation:

Alloys are, for example, generally harder than pure metals. They are made up of atoms of different sizes, rather than being uniform. This means that the layers of atoms cannot slide over each other easily, making the whole alloy much stronger than any of the pure metals that the alloy contains in isolation. Alloys also tend to have better corrosion resistance than pure metals, and are more versatile for manipulating into different forms.
