Music wire is straightened, hardened spring steel wire. Originally, this material was intended for strings in musical instruments, but now it is primarily used in manufacturing spiral springs. Music wire is made from steel with high carbon content. It is pulled through a die to form a thin wire in a process known as "cold drawing" because it occurs at room temperature. Then, it is heat-tempered. Music wire can endure high tension and stress repeatedly without losing its strength or elasticity. As the highest grade of spring wire, it is low in sulfur and phosphorus. Though its tensile strength when hard drawn is 225,000 to 400,000 psi, it is flexible enough to bend 180° without cracking. Additionally, it can wind into a close helix with an inside diameter 1 to 1.5 times the diameter of the wire. This wire typically is specified using the outside diameter. Due to its strength, this material must be cut by a cutting wheel or carbide jawed cutters. It must be stored in protective oil.
Markets & Applications ▼
Music wire is a versatile, affordable spring steel wire useful in a variety of high-stress applications. It is most frequently used in the manufacturing of spiral springs is but also used for pins, stiffening rods, compression springs and extension springs.
