Curt Mangan 9.5-46 Nickel Wound Set
Nickel Wound strings are created by wrapping Nickel-Plated Steel alloys around a hex-shaped core wire which is made from tin-plated high-carbon steel (same as plain strings, but hex-shaped). The ?core-to-wrap? ratio is the combined diameters of the core wire and the wrap wire which creates the overall diameter of the string.
