ASTM B863 Grade 23 titanium wire is high-strength alpha-beta Ti-6Al-4V ELI wire with UNS designation R56407. ELI means Extra Low Interstitial; tighter control of oxygen, nitrogen, hydrogen and iron supports improved ductility, fracture toughness and low-temperature behavior while retaining high specific strength.<\/p>

Grade 23 shares the nominal Al-V alloy system with Grade 5, but chemistry limits and property requirements are not interchangeable. Wire properties depend on diameter, cold reduction, annealed condition, microstructure, surface quality and test conditions. ASTM B863 Grade 23 wire does not automatically comply with ASTM F136, ISO 5832-3, AMS, aerospace or welding-consumable specifications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Main Characteristics<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
  • High specific strength:<\/strong> Density is about 4.42 g\/cm\u00b3 and a representative annealed tensile strength is about 828 MPa, useful for weight-sensitive precision wire parts.<\/li>
  • Tighter interstitial control:<\/strong> Compared with Grade 5, lower limits for oxygen, nitrogen, hydrogen and iron support ductility, fracture toughness, fatigue behavior and low-temperature reliability.<\/li>
  • Good general corrosion resistance:<\/strong> The passive oxide film performs well in seawater, humid atmosphere and many neutral chlorides; strong reducing acids, fluoride media and hot tight crevices require specific evaluation.<\/li>
  • Weldable with strict shielding:<\/strong> Qualified inert-gas fusion, resistance or laser welding may be used; the pool, root and hot heat-affected zone must be protected from oxygen, nitrogen, hydrogen and carbon contamination.<\/li>
  • Properties adjustable by heat treatment and cold work:<\/strong> Annealed, stress-relieved and agreed solution-treated-and-aged conditions differ in strength and ductility; plate, bar or medical-specification data are not automatic wire guarantees.<\/li>
  • Suitable for critical uses only with added controls:<\/strong> Aerospace, medical and fatigue-critical parts commonly require additional melt practice, microstructure, NDT, surface, cleanliness and quality-system requirements.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Aluminum and vanadium:<\/strong> Al stabilizes alpha and contributes strength; V stabilizes beta and provides heat-treatment response. Acceptance follows 5.5-6.5% Al and 3.5-4.5% V.<\/li>
    • Interstitial elements:<\/strong> Grade 23 limits O, N and H to support toughness and ductility. ELI does not mean interstitial-free, and producer typical values do not replace ASTM maxima.<\/li>
    • Iron and residuals:<\/strong> These affect microstructure, strength and lot consistency and must be checked against the standard and material report.<\/li>
    • Titanium content:<\/strong> ASTM states Titanium: Balance. A fixed titanium percentage calculated from nominal chemistry is not an untested product guarantee.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      Typical Applications<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
      \n\t\t\t\t\t\t\t\t\t
      • High-strength lock wire, locating wire and precision parts for aerospace assemblies;<\/li>
      • specially validated wire parts for low-temperature, fatigue- or fracture-critical service;<\/li>
      • medical-device and surgical-implant parts only when ASTM F136, ISO 5832-3, customer drawings and regulatory requirements are separately met;<\/li>
      • high-performance fasteners, springs, clips and lightweight connectors;<\/li>
      • high-strength corrosion-resistant wire parts for marine, chemical and energy equipment;<\/li>
      • precision parts requiring drawing, coiling, weaving, bending or flattening;<\/li>
      • welding filler wire only when AWS A5.16 ERTi-23 requirements are met;<\/li>
      • special assemblies made to customer drawings and validated by fatigue, forming, corrosion or functional testing.<\/li><\/ul>

        Application boundary:<\/strong> ASTM B863 Grade 23 wire is not automatically implant-grade material, aerospace-qualified material or welding filler. Those uses separately require ASTM F136, ISO 5832-3, AMS, AWS A5.16, customer drawings and quality-system requirements.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
