Question

Alloys have some advantages over a pure metal. Explain this statement with two examples.

Answer 1

We know that an alloy is a uniform mixture of two or more metals or a metal with a non-metal. An alloy usually has different properties from that of the pure metal with which it is made. Alloys have some advantages over pure metals. Let us explain this with two examples.
1. Stainless steel, an alloy of iron with nickel and chromium, is much stronger than iron and does not corrode at all. Thus, stainless steel has replaced iron in the manufacture of utensils, nettings, etc.
2. Brass (copper + zinc) and bronze (copper + tin) are alloys of copper. They are harder, stronger and have higher resistance to corrosion as compared to copper. Thus, these alloys are used for making statues, medals, decorative articles, etc.
