ASTM F67 Grade 1 unalloyed titanium wire is wrought commercially pure titanium wire used to manufacture surgical implants, UNS R50250. Grade 1 has the lowest strength and greatest ductility and cold-workability among the four unalloyed grades in ASTM F67; its properties are controlled principally through limits on oxygen, iron, nitrogen, carbon and hydrogen.<\/p>

The material offers good biocompatibility, resistance to physiological corrosion, bendability and formability for medical-device raw material requiring high ductility or fine diameters. ASTM F67 compliance applies to the wire raw material; it does not mean a finished implant has completed design verification, biological evaluation, cleaning, sterilization or regulatory approval.<\/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 ductility and formability:<\/strong> Annealed Grade 1 has high specified elongation and is suited to bending, coiling, weaving, flattening and other controlled cold-forming operations.<\/li>
  • Controlled unalloyed chemistry:<\/strong> No nominal alloying addition is made; O, Fe, N, C and H are controlled to balance strength, ductility, toughness and drawing consistency.<\/li>
  • Good biocompatibility:<\/strong> A stable TiO2 passive film helps limit ion release in physiological environments. The finished device still requires applicable biological evaluation.<\/li>
  • Good corrosion resistance:<\/strong> Performance is generally excellent in saline, body fluids and many chlorides, but crevices, fretting corrosion, dissimilar-metal coupling and fluoride exposure require device-level evaluation.<\/li>
  • Good weldability:<\/strong> Qualified inert-gas, laser or resistance welding may be used; heat input and shielding of fine wire must be tightly controlled to prevent O, N, H and C contamination.<\/li>
  • Lower strength than higher grades:<\/strong> Grade 1 is selected for ductility, not maximum load capacity. Load-bearing implants require design verification using actual load, fatigue, geometry, surface and service-life conditions.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Technical references:<\/strong> ASTM F67 official scope and producer data for Grade 1 \/ UNS R50250.<\/li>
    • Oxygen and iron:<\/strong> Oxygen is an important interstitial strengthener in unalloyed titanium; iron also raises strength, but higher content can reduce ductility. Grade 1 uses lower limits to retain formability.<\/li>
    • Nitrogen, carbon and hydrogen:<\/strong> These elements require strict control. Excess content raises hardness and reduces ductility; hydrogen may promote hydrides and embrittlement.<\/li>
    • Residual elements:<\/strong> Each and total limits must be controlled. Testing only the principal impurities does not satisfy the full chemistry requirement.<\/li>
    • Titanium content:<\/strong> The specification states Titanium: Balance. A nominal purity claim does not replace heat-specific chemical analysis and the material report.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
