The Material of Choice for Corrosive Environments

Music wire is a high-carbon steel alloy, which finds its major use in manufacturing springs. It is known to offer uniform and high tensile strength, and high elastic limit. Due to this, a music wire can endure high stress, still delivers outstanding performance under several normal recurring applications. SMSC has an array of different types of springs  made from this material.
