Tinsel wire is a product in which a flat wire (foil) manufactured by rolling an electric copper wire that has been drawn to a fineness of 0.18 mm to 0.025 mm is spirally wrapped around a center thread of another material.
It is a light, flexible and flexible lead wire. The foil can be wound up to 4 layers, and copper foil yarn can be twisted together. In addition, the combination of foil (various plating and various alloys) and center yarn (polyester, aramid, etc.) has various properties such as bending resistance, heat resistance, and flame resistance, and is used for various purposes.
