Tinsel wire is a form of electrical wire used when maximum mechanical flexibility is desired. It is commonly found in cords used for telephones cables as, Line Cords, Straight Cords, Extension Cords, Coil Cord, Curl Cord, Coiled Cord, especially the handset cords. Because of its extreme flexibility, it is very resistant to failing as a result of metal fatigue. In this way it is different than ordinary stranded wire or, especially, solid wire.
