\n\t\t\t\t\t\t\t\t\t

ASTM F1295 titanium wire is wrought Ti-6Al-7Nb alpha-beta alloy wire for surgical implant manufacture, UNS R56700. Niobium replaces the vanadium used in Ti-6Al-4V. The alloy combines high specific strength, good corrosion resistance and established medical-processing capability. Ti-6Al-7Nb must not be identified as ASTM Grade 5 or Grade 23.<\/p>

Wire may be supplied in coils, on spools or as cut straight lengths for orthopedic, trauma, spinal, dental and other surgical-implant components. ASTM F1295 controls implant raw material; the finished device still requires validation of size, condition, cold work, microstructure, surface integrity, fatigue, cleaning, sterilization, biological safety and regulatory compliance.<\/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
  • Vanadium-free medical alpha-beta alloy:<\/strong> Niobium acts as the beta stabilizer. ASTM F1295 Ti-6Al-7Nb is a different alloy from ASTM F136 Ti-6Al-4V ELI and ASTM F1472 Ti-6Al-4V; specifications, identification and reports are not interchangeable.<\/li>
  • Controlled alpha-beta chemistry:<\/strong> Al, Nb, Ta, Fe and the interstitial elements O, C, N and H require heat-specific control for consistent strength, ductility, microstructure and drawing response.<\/li>
  • Good biocompatibility:<\/strong> A stable TiO2 passive film and extensive clinical use support its role as a common implant material. The finished device still requires biological evaluation under applicable regulations and standards such as ISO 10993.<\/li>
  • Good corrosion resistance:<\/strong> Performance is generally excellent in saline, body fluids and many chloride environments, but fretting, crevices, dissimilar-metal coupling, fluoride media and surface contamination require device-level evaluation.<\/li>
  • Weldable with strict shielding:<\/strong> Qualified laser, resistance, electron-beam or GTAW\/TIG processes may be used. The pool, root and hot heat-affected zone require full inert-gas protection. Fine-wire joining must also control local melting, heat-affected-zone embrittlement and dimensional distortion.<\/li>
  • High strength with limited cold formability:<\/strong> Wire can be drawn, straightened, coiled and cold-bent to a limited extent, but has less room-temperature forming margin and greater springback than unalloyed titanium. Performance depends on diameter, annealed\/cold-worked condition, surface quality and residual stress; complex forming requires lot-specific process qualification.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Technical basis:<\/strong> Current ASTM F1295 scope and requirements; typical physical values additionally reference engineering data for Ti-6Al-7Nb \/ UNS R56700.<\/li>
    • Aluminum and niobium:<\/strong> Al is 5.50-6.50% and Nb is 6.50-7.50%. Their balance produces an alpha-beta microstructure; chemistry uniformity and thermomechanical processing affect drawing response and final-device properties.<\/li>
    • Interstitials and iron:<\/strong> O, Fe, C, N and H affect strength, ductility, toughness and hydrogen-embrittlement risk. The hydrogen maximum is 0.009%; values copied from conventional Ti-6Al-4V are not applicable.<\/li>
    • Tantalum:<\/strong> Ta is limited to 0.50% maximum. Do not add yttrium or generic \u201ceach\/total other element\u201d limits unless they appear in the contract or applicable edition.<\/li>
    • Titanium content:<\/strong> The specification states Titanium: Balance. A nominal grade or medical-grade claim does not replace heat-specific analysis, the material report and contract testing.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      \n\t\t\t\t\t\t\t\t\t

      ASTM F1295 specifies minimum room-temperature tensile properties for bar and wire by condition. Annealed and hot-worked material: UTS 900 MPa, 0.2% yield strength 800 MPa, elongation 10% and reduction of area 25%, all minimum. Cold-worked material: UTS 1100 MPa minimum; yield strength, elongation and reduction of area remain 800 MPa, 10% and 25% minimum. Other conditions may be agreed. For material under 1.6 mm in diameter or thickness, the elongation method is negotiated; typical values must not replace acceptance requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
