* Tin

* Lead

* Silver

* Copper

* Aluminum

The specific metal used depends on the fuse's intended application and the desired melting point. For example, tin and lead are commonly used in low-amperage fuses, while silver and copper are used in higher amperage fuses due to their higher conductivity and melting points.

The wire is designed to melt when the current flowing through it exceeds a predetermined limit, breaking the circuit and preventing damage to other components.
