REDwire Key factors to consider before working with music wire

Music wire is known for its high tensile strength and high elastic limit.

Music wire is the most common and readily available wire today. 

The high-quality, high-carbon spring wire is known for its high tensile strength and high elastic limit. It can withstand high stresses under repeated loadings, and will continue to perform well under many normal cyclic applications. 

As strong as it is, however, there are several design considerations to keep in mind when working with music wire

  • The maximum working temperature for music wire is 120 degrees C (250 degrees F). At this temperature, the spring will lose approximately five per cent of its load.
  • This material is used for cold-coiled springs only.
  • This material should not be welded. 
  • Springs made from music wire can successfully undergo a number of plating processes — both Electro-mechanical and Non-electro-mechanical.
  • Music wire can be ordered in a pre-plated finish — a great feature for springs or wire forms that will not plate successfully due to tangling, nesting or distortion during the mechanical plating process.
  • It can be ordered in round, flat and square shapes, as well as special shapes.
  • Music wire has very limited corrosion resistance.
  • Shot-peening can be used on music wire to improve fatigue life.

Maximum stress levels must be considered when designing a spring. Setting, fatiguing or breakage can occur when springs are worked beyond their optimal range. If you keep the above points in mind when working with music wire, you will be on your way to a successful application.
