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

ASTM F1295-24 titanium bar is wrought Ti-6Al-7Nb alpha-beta alloy bar for surgical implant manufacture, UNS R56700. Aluminum stabilizes alpha and niobium stabilizes beta. Replacing vanadium with niobium retains high specific strength, good corrosion resistance and established processing behavior while providing a titanium-aluminum-niobium alloy system suited to long-term medical applications.<\/p>

ASTM F1295 covers bar, wire, sheet, strip and plate in annealed, cold-worked or hot-worked conditions. Bar is normally round, flat or another shape from 4.76 to 102 mm (0.188 to 4.0 in) in diameter or thickness; special sizes may be ordered. It is widely used as machining stock for joint replacement, trauma, spinal, dental and other implant devices. The finished device still requires design, fatigue, biological, cleaning, sterilization and regulatory validation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Medical-use boundary:<\/strong> ASTM F1295-compliant bar is medical-device raw material, not an approved finished implant. The device manufacturer remains responsible for design, machining, fatigue, surface treatment, cleaning, sterilization, biological evaluation, risk management and regulatory compliance.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\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> Approximately 7% Nb replaces V as the beta stabilizer. Mechanical and metallurgical behavior is similar to Ti-6Al-4V, while the surface oxide system includes stable TiO\u2082, Al\u2082O\u2083 and Nb\u2082O\u2085. Selection must still follow device design, regulation and clinical risk assessment.<\/li>
  • Controlled chemistry:<\/strong> Al is 5.50-6.50% and Nb is 6.50-7.50%, with limits on Ta, Fe, O, C, N, H and residuals. Hydrogen is sampled from finished product to control hydrogen pickup and embrittlement risk.<\/li>
  • Good biocompatibility:<\/strong> Ti-6Al-7Nb has a long history in devices contacting bone and soft tissue, and niobium oxide is stable and sparingly soluble. ASTM F1295 raw-material compliance does not approve a finished implant; applicable biological evaluation such as ISO 10993 remains required.<\/li>
  • Good corrosion resistance:<\/strong> A dense, renewable titanium\/niobium-enriched passive film generally performs well in saline, body fluids and many chlorides. Fretting, wear, crevices, fluoride media, dissimilar metals and contamination still require device-level evaluation.<\/li>
  • Weldable with contamination control:<\/strong> Annealed material can be joined by qualified GTAW\/TIG, laser, electron-beam or resistance processes. Fully shield the pool, root and hot heat-affected zone against O, N, H and C pickup and resulting ductility loss.<\/li>
  • High strength with controlled processability:<\/strong> Annealed and hot-worked conditions provide a stable strength\/ductility baseline; cold work raises tensile strength. Bar can be forged, rolled, drawn, machined and cold formed to a limited degree. Processing resembles Ti-6Al-4V, with strict control of temperature, residual stress, alpha case and surface defects.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Aluminum and niobium:<\/strong> Al is 5.50-6.50% and Nb is 6.50-7.50%. Aluminum stabilizes alpha and niobium stabilizes beta. Homogeneity, beta transus and thermomechanical processing jointly determine the final alpha-beta microstructure and properties.<\/li>
    • Tantalum and interstitials:<\/strong> Ta\u22640.50%, Fe\u22640.25%, O\u22640.20%, C\u22640.08%, N\u22640.05% and H\u22640.009%. The stringent hydrogen limit requires control of hydrogen pickup during pickling, heat treatment, cleaning and storage.<\/li>
    • Residuals and titanium:<\/strong> Common requirements are \u22640.10% for each residual and \u22640.40% total, with titanium as balance. Heat-specific reports should cover every required element and remain traceable to product identification.<\/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

      ASTM F1295 specifies room-temperature minima for bar and wire by delivery condition. Annealed and hot-worked material require \u2265900 MPa ultimate tensile strength, \u2265800 MPa 0.2% yield strength, \u226510% elongation and \u226525% reduction of area. Cold-worked material requires \u22651100 MPa ultimate tensile strength, with the other minima remaining \u2265800 MPa, \u226510% and \u226525%. Alternative conditions may be agreed between purchaser and supplier.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

      Important:<\/strong> These are condition-specific standard minima for bar and wire.
