For over 50 years, M & S Spring Company has manufactured torsion springs, compression springs, and extension springs using music wire because of its high tensile strength and fatigue life. Music wire springs can withstand high load stresses compared to other materials, which makes this material best suited for cyclic applications. Music wire is cold drawn. Although this material is versatile, it’s not recommended for service temperatures above 250°F (121°C). M & S Spring Company’s music wire springs meet ASTM A228 standards.
