。[Prior art] As stated in the Japan Institute of Metals (Metals Handbook (revised December 20, 1981, 7l54th edition ρ.1007) J), fuses have conventionally been made of lead, zinc or tin lead. Alloys are commonly used. Fuse conductors made of these metals or alloys are blown by the Joule heat of the overcurrent, opening an electrical circuit. When attempting to accurately determine the fusing current without being affected by the outside temperature, a fuse conductor made of tungsten wire may be used. Furthermore, wood metal, which has r8gIA at low temperatures, is used for fuses that melt due to overheating of the heating atmosphere.

ム合金と同様、良好である。[Operations and Effects of the Invention] Since the second phase metal is less than 0.5 Wt% in the same phase state with respect to aluminum or aluminum alloy; since it uses a metal that has only flash solid solubility and a large density difference, it is difficult to remove the alloy from the molten state. When solidified, the aluminum or aluminum alloy and the second phase metal do not form a solid solution with each other, and each exists as an independent metal in the same phase state. Such second phase metals include, for example, lead, bismuth, or indium. According to the second revised edition of the "Metal Data Book" compiled by the Japan Institute of Metals, the melting point of lead is 327.6°C, the melting point of bismuth is 271.5°C, and the melting point of indium is 156.8°C.
It is. Therefore, when the fuse conductor of the present invention is humidified by an overcurrent, the second phase metal, which is a low melting point metal, melts at its melting point and ruptures the aluminum or aluminum alloy jacket I due to volumetric expansion, forming the conductor. Skip the line. In this way, it exhibits excellent fusing characteristics. In addition, since the second phase metal is arranged in the matrix of aluminum or aluminum alloy in the form of fibers or grains, the wire drawability into A-wire or ultra-fine wire is as good as that of aluminum or aluminum alloy. .
