Music wire of this type is drawn and tempered to deliver consistent tensile strength and spring-back characteristics across the coil. At 0.047 inches in diameter, this wire is well suited for applications requiring tight dimensional tolerances and reliable elastic performance. It meets ASTM A228 standards, which govern the mechanical properties of high-quality carbon steel music wire. The coil ships at approximately 1.05 pounds and is packaged as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis wire coil is used across a wide range of mechanical and fabrication applications where consistent diameter and temper are critical. Typical uses include spring fabrication, wire forms, light mechanical assemblies, and general maintenance shop work. It is commonly stocked by HVAC and mechanical contractors for forming small tension and compression springs during equipment repairs, as well as by industrial maintenance teams for custom wire-form fabrication.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh carbon steel construction tempered to ASTM A228 for consistent tensile and spring properties\u003c\/li\u003e\n  \u003cli\u003e21 gauge at 0.047 inches diameter for precise fitment in small-form spring and wire applications\u003c\/li\u003e\n  \u003cli\u003e170-foot coil length provides substantial working stock from a single package\u003c\/li\u003e\n  \u003cli\u003eASTM A228 compliance ensures standardized mechanical performance expectations\u003c\/li\u003e\n  \u003cli\u003eSingle-coil packaging with an MOQ of 1 for flexible purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose high carbon steel music wire coil suitable for spring fabrication, wire-form production, and mechanical repair applications requiring ASTM A228-compliant 21-gauge wire.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCut and form music wire using appropriate safety gloves and eye protection, as cut ends are sharp and the wire stores significant spring energy. Use proper wire cutters or shears rated for high carbon steel to avoid tool damage or wire deformation at the cut point. When forming springs or wire shapes, work in a controlled environment and follow applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Tempered Music Wire Coil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 170 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31152200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION BRAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION BRAND","offers":[{"title":"Default Title","offer_id":51540883964210,"sku":"21047","price":23.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec232edaecc7dd71eb2f39c4016e6ea0_43feaca5-f1b4-4a1c-bb38-5dd2f1fe2d64.jpg?v=1785865404","url":"https:\/\/voomisupply.com\/products\/precision-brand-21047-music-wire-coil-21-gauge-170-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
