ASTM B863 Grade 5 titanium wire is Ti-6Al-4V alpha-beta titanium-alloy wire with UNS designation R56400. Grade 5 is one of the most widely used titanium alloys. Aluminum stabilizes the alpha phase and vanadium stabilizes the beta phase. It combines high specific strength, good fatigue performance, intermediate fracture toughness, corrosion resistance and weldability. Final properties depend on chemistry, melt quality, thermomechanical history, microstructure, diameter, cold reduction and heat-treatment condition.<\/p>

Compared with commercially pure Grade 4, Grade 5 provides substantially higher strength but generally lower room-temperature formability and greater sensitivity to notches, surface damage, processing heat and high-temperature contamination. Grade 5 wire may be used for high-strength fasteners, lock wire, spring-like or formed parts and aerospace components. Filler, medical or flight-critical uses require the applicable AWS, medical, AMS or customer specification in addition to ASTM B863.<\/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> Annealed Ti-6Al-4V is substantially stronger than commercially pure titanium while its density is only about 4.42-4.43 g\/cm\u00b3, making it useful where both weight and load capacity matter.<\/li>
  • Good fatigue and general engineering performance:<\/strong> With controlled microstructure, surface condition and residual stress, the alloy can provide good fatigue performance; design allowables must come from the applicable specification and validated data.<\/li>
  • Corrosion resistance with low density:<\/strong> It resists general corrosion in seawater, humid atmosphere and many chloride environments, but this does not establish immunity in every crevice, reducing acid or hot-salt condition.<\/li>
  • Weldable with strict shielding:<\/strong> Qualified fusion-welding methods may be used, with complete inert-gas protection of the weld and hot heat-affected zone and strict prevention of oxygen, nitrogen, hydrogen, carbon and iron contamination.<\/li>
  • Useful low-temperature properties:<\/strong> Ti-6Al-4V retains useful strength and toughness at low temperature. Fracture-critical service may require Grade 23 ELI or another specified material and must not substitute Grade 5 by name alone.<\/li>
  • Heat-treatable:<\/strong> Unlike commercially pure titanium, Grade 5 can be strengthened and its microstructure modified by solution treatment and aging. Annealed, stress-relieved and solution-treated-and-aged conditions are not interchangeable and the ordered 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 enables microstructure and properties to be controlled by thermomechanical processing and heat treatment.<\/li>
    • Oxygen, nitrogen, iron and carbon:<\/strong> Affect strength, hardness, toughness and processability. Excess content or high-temperature contamination can reduce ductility and notch performance.<\/li>
    • Hydrogen:<\/strong> Must be strictly controlled. Improper pickling, heat treatment or electrochemical exposure can promote hydrogen pickup and hydride risk.<\/li>
    • Titanium content:<\/strong> ASTM states Titanium: Balance. Ti-6Al-4V is a nominal alloy name; acceptance follows each specified elemental range and titanium by difference, not a separate guarantee such as ‘approximately 90% Ti.’<\/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 5 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 5 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

      • Aerospace lock wire, tie wire, fastener stock and small high-strength structural parts;<\/li>
      • high-strength connectors, pins, retaining rings, clips and drawing-defined formed parts;<\/li>
      • spring-like, coiled and precision wire components requiring a high strength-to-weight ratio;<\/li>
      • corrosion-resistant high-strength connection or locating parts for marine, chemical and energy equipment;<\/li>
      • lightweight parts for motorsport, bicycles, sporting goods and high-performance consumer products;<\/li>
      • critical components only when the applicable aerospace, medical or customer material specification is also satisfied;<\/li>
      • welding filler wire when AWS A5.16 ERTi-5 or another applicable consumable specification is met;<\/li>
      • high-strength wire parts made to customer drawings and validated by forming, fatigue or functional testing.<\/li><\/ul>

        Application boundary:<\/strong> ASTM B863 compliance alone does not make Grade 5 wire implant grade, aerospace grade or qualified welding filler. Medical, aerospace or filler-wire uses may additionally require ASTM F1472, ASTM F136\/ISO 5832-3 when Grade 23 ELI is specified, AMS, AWS A5.16 ERTi-5, customer material specifications, drawings and the appropriate quality system.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
