Music Wire

Music Wire is a common name for high carbon spring wire. This product is used for countless spring applications.  It received its name because it was originally used for Piano wire.  This high tensile wire can withstand temps up to 250 degrees Fahrenheit, has high fatigue life, as well as, take severe bends without cracking.

Music wire is typically phosphate coated to assist lubrication in the spring winding process.  It can be plated post-production or purchased in pre-plated state with additional corrosion resistant properties such as zinc.

The general consensus is that music wire is one of the best, toughest, and most widely preferred materials for all sizes of springs. It has one of the highest tensile strengths and can withstand higher stresses under repeated loading than other spring materials.

JIS G3522 classifies them into SWP-A,SWP-B and SWP-C.

Application

Aside from its use in pianos, this wire is most frequently bent into springs for high-tension applications because it can bear repeated heavy loads. (For example, music wire is often used in spring-loaded windows.)
