What Is The Material Of The Fuse?

Cutout fuse is usually made of low melting point metals such as lead, tin or alloys.

In order to ensure the safe operation of the circuit, the fuse in the fuse needs to be made of fusible metal materials. These materials have a low melting point so that they can be melted in time when the current is too large, thereby protecting the circuit. Common fuse materials include lead, tin and their alloys. For example, lead-antimony alloy is widely used because of its low melting point characteristics. When the current in the circuit exceeds a certain limit, this alloy will quickly melt and automatically cut off the circuit to ensure the safety of the circuit.

In addition, in order to enhance the conductivity and corrosion resistance of the fuse, a small amount of copper cap is sometimes added to the fuse. These designs enable the fuse to have good conductivity and corrosion resistance while playing a protective role.
