Answer:
Fuse wire is made of a tin-lead alloy and not copper because of the following reasons: 1. They have high resistance due to high resistance the wire heats up quickly, when large current flows. ... They have low melting point which melts and breaks off the circuit if the current is larger than the safety limit

Explanation:
It is so because, tin and lead have low boiling point.
When the current exceeds its heating limit it melts down and stops the flow of current thus helping in preventing the damage of electric appliances
