Question

Give two properties of alloys which are different from its constituent metals.

Answer 1

Disclaimer: Any two of the following properties of alloys can be used to answer this question.

Alloys usually have different properties from their constituent metals. The properties of alloys are

1. Alloys have better resistance to corrosion than the metals from which they are made.
2. Alloys are stronger and harder as compared to their constituent metals.
3. Alloys have lower melting points than their constituent metals.
4. Alloys are not as good conductors of electricity as compared to their constituent metals.

For example, steel (which is an alloy of iron metal) is more resistant to corrosion, stronger and harder than pure iron metal.
