A superconducting wire or strip with loss-free current passage at normal ambient temperatures and higher consists of a material of a normally conducting metal whose ion structure is changed so that the conductor at normal ambient temperature has its characteristic transition temperature corresponding to the molecular construction of this material. At normal temperature in a soft, extensible and deformable or fluid state, preferably such a one of high atomic mass, like lead, or an alloy between two or more materials conducting at normal temperature, finds application. The wire is heated continuously by current increase during the whole process and subsequently is cooled suddenly to its characteristic transition temperature directly or indirectly by a gaseous or liquid medium, until the superconducting ability at normal ambient temperature is attained.
