Music Spring Wire

Wire made from high-carbon (.70-1.0) cold-drawn steel with high tensile strength. This wire is manufactured for the production of springs subject to high stress, and or requiring good fatigue properties. Historically, the wire is patented and cold drawn to its finish size. The wire must pass rigorous testing to be classified as music spring wire. Note: the term reportedly came about when a spring manufacturer that had good results using piano wire asked for more of that “music spring wire.”
