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

ASTM B863 Grade 9 titanium wire is medium-strength Ti-3Al-2.5V titanium-alloy wire with UNS designation R56320. It contains 2.5-3.5% aluminum and 2.0-3.0% vanadium and is commonly treated as a cold-workable alpha-beta or near-alpha engineering alloy. It bridges the fabricability and weldability of commercially pure titanium and the higher strength of Grade 5, with common uses in aerospace hydraulic systems, lightweight tubing, pressure components and performance products.<\/p>

Grade 9 is stronger than the common commercially pure grades but weaker than typical Grade 5, and usually offers better cold formability than Grade 5. Wire properties depend on diameter, cold reduction, stress-relieved or annealed condition, heat treatment, microstructure and surface quality. ASTM B863 Grade 9 wire does not automatically satisfy aerospace-tubing, pressure-equipment, medical-device or welding-consumable specifications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Grade-equivalence note:<\/strong> Grade 9 is sometimes informally compared with TA18 in the Chinese market. ASTM Grade 9 and Chinese GB\/T grades must be certified to their own specifications and should not be declared fully equivalent without clause-by-clause comparison.<\/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
  • Medium strength and high structural efficiency:<\/strong> Density is about 4.48 g\/cm\u00b3 and an annealed reference tensile strength is about 620 MPa, supporting weight-sensitive parts that also need useful formability.<\/li>
  • Good cold workability:<\/strong> Ti-3Al-2.5V is more suitable than Ti-6Al-4V for cold drawing and forming, but bend radius, area reduction and intermediate annealing still require process validation.<\/li>
  • Good general corrosion resistance:<\/strong> It performs well in seawater, humid atmosphere and many neutral chlorides, broadly near CP titanium behavior, but reducing acids and extreme crevice conditions require specific evaluation.<\/li>
  • Good weldability:<\/strong> Qualified inert-gas fusion or resistance welding can be used; hot weld metal and heat-affected zones must be protected from oxygen, nitrogen, hydrogen and carbon contamination.<\/li>
  • Useful over a broad temperature range:<\/strong> It has good low-temperature behavior and retains useful strength at moderate temperature, but allowable temperature and stress must come from the applicable design code.<\/li>
  • Properties can be adjusted by cold work and heat treatment:<\/strong> Annealed, cold-worked stress-relieved (CWSR), and solution-treated-and-aged conditions differ in strength and ductility and are not interchangeable; the purchase condition must be explicit.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Aluminum and vanadium:<\/strong> Aluminum stabilizes alpha and contributes strength; vanadium stabilizes beta and supports processing and heat-treatment response. Acceptance follows the specified ranges, not merely the nominal 3Al-2.5V name.<\/li>
    • Oxygen, iron and nitrogen:<\/strong> Affect strength, hardness, ductility and notch performance. Grade 9’s relatively low oxygen limit helps balance strength with fabricability.<\/li>
    • Hydrogen:<\/strong> Must be strictly controlled. Improper pickling, heat treatment or electrochemical exposure can promote hydrogen pickup, loss of ductility and hydride formation.<\/li>
    • Titanium content:<\/strong> ASTM states Titanium: Balance. A fixed titanium percentage calculated from the nominal alloy name 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

      ASTM B863 includes tensile, elongation and hardness requirements for Grade 9 wire. Properties vary with diameter and delivery condition. Formal acceptance must therefore follow the ordered annealed or cold-worked condition, applicable size range, test method and the official tables of the specified standard edition.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

      Important:<\/strong> The values above are representative annealed Grade 9 data and are not ASTM B863 wire acceptance values. Diameter, cold reduction and final annealing materially affect strength, elongation and hardness. Quotations, contracts and MTRs should identify diameter, tolerance, condition, surface, coil weight or cut length, and inspection requirements.<\/p><\/div>\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
      • Lock wire, locating wire and small high-strength parts for aerospace hydraulic and pneumatic systems;<\/li>
      • wire or formed stock for lightweight tubing, fittings, clips and pressure systems;<\/li>
      • high-strength lightweight parts for bicycles, motorsport and sporting goods;<\/li>
      • corrosion-resistant medium-strength connectors for marine, chemical and energy equipment;<\/li>
      • precision wire parts requiring drawing, coiling, bending or flattening;<\/li>
      • critical parts only when additional medical, aerospace or customer specifications are satisfied;<\/li>
      • welding filler wire when the applicable Ti-3Al-2.5V classification under AWS A5.16 is met;<\/li>
      • special wire assemblies made to customer drawings and validated by forming, fatigue, pressure or functional testing.<\/li><\/ul>

        Application boundary:<\/strong> ASTM B863 Grade 9 wire is not automatically qualified aerospace hydraulic tubing, implant material, pressure-equipment material or welding filler. Such uses separately require the applicable AMS\/tubing, medical, ASME\/design-code, AWS A5.16, customer drawing and quality-system requirements.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
