The wire or tape used in these fuses is chiefly lead, although hardened with the addition of a small percentage of another hardening metal such as tin or antimony. Suitable termi- nals are provided at the ends of the tube for terminating the fusible conductor. By eating through the lead the insects make it necessary to replace the fuse just as if it had been operated in its regular.
