BlackAnnealedSteelWireDeriving its name from its use in piano strings, music wire is a reliable, high-tensile, high-carbon steel wire most commonly used in springs because of its ability to withstand repeated loads and high stress while still retaining its resiliency and elasticity. Music wire is cold-drawn (mostly to thin diameters), then heat-treated to patent specifications, bent and curved into springs. While this wire is most commonly used as spring material in industrial applications and manufacturing, it is also used for hobby and home use for everything from crafting to kitchen slicers. Popular for its affordability and durability, music wire is a great all-around solution for a wide range of high-stress uses.


  • Springs that experience repeated loading, stretching and relaxing (e.g., springs for windows to enable opening and shutting)
  • Piano strings
  • Hobby applications (e.g., radio-controlled aircraft, model railroads)
  • Surgical tools
  • Fishing lures
  • Kitchen utensils (e.g., cheese slicers)
  • Multiple other industrial applications, particularly where springs are involved


  • Applications under cold or hot temperature extremes (maximum recommended operating temperature is 250˚F)
  • Applications with high-impact or shock loads

What is music wire used for? Music wire is a highly versatile type of wire, however as the name implies, it is best known for only one of its uses. It is made from high carbon steel, making it ideal for high-stress applications such as piano strings. Is piano wire the same as music wire? Also known as piano wire, music wire consists of tempered, high-carbon spring steel. In the past, most pianos were made of iron-based wire. In the 1830s, music wire began to replace this iron-based wire. What grade of steel is music wire? ASTM A228 Steel Cold drawn. High tensile strength and uniform mechanical properties. Music wire springs are not recommended for service temperatures above 121°C (250°F). Applications: High quality springs and wire forms subject to high stresses or requiring good fatigue properties.
