Abstract: A tinsel wire is formed of a central fiber and at least one metallic lead wire combined with the central fiber. The central fiber is made of graphene. Therefore, the tinsel wire has advantages of high electric conductivity, great strength, and resistance against high temperature. In addition, the metallic lead wire of the tinsel wire avoids the drawback that the graphene is not easily soldered, thus guaranteeing the soldering effect of the tinsel wire.
