Define alloys. List the properties of alloys that make them useful over pure metals ? Explain this fact with suitable examples.

Text Solution

Verified by Experts

Alloys are homogeneous mixture of two or more metals or a metal and a non-metal that cannot be separated into their components by physical methods.
The properties that make them useful over metal are
(i) The electrical conductivity
(ii) Melting point of an alloy is less than that of a pure metal.
e.g. Brass and Bronze are not good conductors of electricity whereas copper is used in making electrical circuit.
e.g., Solder has a low melting point.
