Q

Why alloys are preferred

A

Alloys are stronger and harder
They are made of different elements with different particle sizes
This disrupts the regular arrangement of particles
Hence the layers cannot slide over one another when a force is applied

Q

Why is melting point high

A

high melting point.
it has giant lattice structure with strong electrostatic attraction forces between positive ions and sea of delocalized electrons. Thus a large amount of energy is needed to break these forces
