Description

The present invention relates to the technical field of fuse element materials used in fuses, and more particularly to silver-copper composite tapes and fuse elements.

To ensure the safety of electrical circuits and personnel, electrical circuit designers often place fuses in the circuits. As the most widely applied fusible material for fuses, pure silver tape has excellent circuit fusing ability, excellent anti-oxidation and anti-corrosion properties, which is advantageous in ensuring the peace and safety of electric circuits. However, the price of pure silver material is high, so the production cost of the fuse cannot be reduced, and the fuse will be discarded after it expires, resulting in a large waste of silver resources.
