ASTM B863 Grade 1 titanium wire is an unalloyed commercially pure titanium wire product with UNS designation R50250. Among commonly used CP titanium Grades 1 through 4, Grade 1 has relatively low interstitial-element limits, low strength, and outstanding ductility and formability. At room temperature its structure is predominantly single-phase alpha titanium. Performance is influenced by oxygen, iron, nitrogen, carbon and hydrogen content, grain size, cold reduction and final delivery condition.<\/p>

Grade 1 titanium wire combines low density, excellent corrosion resistance, good joinability and high ductility. It is used for woven mesh, lightly loaded corrosion-resistant connections, electrochemical components, qualified filler applications and precision formed parts. The intended use should be matched to wire diameter, surface condition, required strength or hardness, and downstream processing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Grade-equivalence note:<\/strong> Grade 1 is sometimes informally called TA1 in the Chinese market. ASTM Grade 1 and Chinese GB\/T grades must be certified to their own specifications and should not be declared fully equivalent without a 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
  • Excellent ductility and formability:<\/strong> Annealed Grade 1 wire is suitable for bending, coiling, weaving, flattening and other cold-forming operations. Cold work raises strength and hardness while reducing ductility.<\/li>
  • Excellent corrosion resistance:<\/strong> A dense and stable titanium-oxide passive film forms naturally on the surface and can repassivate when oxygen or moisture is available.<\/li>
  • Low density:<\/strong> Approximately 4.51 g\/cm\u00b3, about 60% of ordinary steel, supporting lightweight corrosion-resistant components and mesh structures.<\/li>
  • Good joinability:<\/strong> Grade 1 can be fusion welded or resistance welded using a qualified procedure, with complete inert-gas protection of hot metal and strict exclusion of oil, moisture and iron contamination.<\/li>
  • Good low-temperature toughness:<\/strong> CP titanium does not normally show the pronounced ductile-to-brittle transition associated with some steels.<\/li>
  • Not significantly strengthened by conventional heat treatment:<\/strong> Strength is controlled mainly by interstitial chemistry, grain size and cold work; annealing restores ductility and relieves drawing stress.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    • Oxygen and nitrogen:<\/strong> Increase strength and hardness, but excessive levels reduce ductility, toughness and formability.<\/li>
    • Iron:<\/strong> Contributes to strength; excessive iron may affect microstructural uniformity and corrosion performance.<\/li>
    • Hydrogen:<\/strong> Must be strictly controlled because excessive hydrogen may form hydrides and increase embrittlement risk.<\/li>
    • Titanium content:<\/strong> ASTM uses \u201cTitanium: Balance.\u201d A fixed statement such as \u201cTi \u226599.5%\u201d should not be used unless supported by the actual heat analysis or an additional producer guarantee.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      ASTM B863 includes requirements for tensile properties, elongation and hardness. 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 typical values above describe a Grade 1 reference material 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

      HTN organizes the supply of ASTM B863 Grade 1 titanium wire according to customer purchase requirements. Material is produced by qualified titanium-mill resources. Original mill test reports, heat traceability, chemistry and performance records can be supplied as agreed. HTN reviews the standard edition, heat number, documents, diameter, tolerance, delivery condition, coil weight or cut length and surface condition, and can arrange independent retesting, cut-to-length service, clean packaging and third-party inspection when required.<\/p>\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
      • Corrosion-resistant mesh, filters and mist eliminators for chemical and marine service;<\/li>
      • electroplating racks, anode baskets, cathode assemblies and electrochemical connections;<\/li>
      • industrial parts requiring coiling, weaving, bending or flattening;<\/li>
      • corrosion-resistant tie wire, locating wire, small connectors and fastening components;<\/li>
      • non-contaminating mesh and components for food, pharmaceutical and high-purity-fluid equipment;<\/li>
      • corrosion-resistant fine-wire parts for vacuum, laboratory and instrumentation equipment;<\/li>
      • welding filler wire where a separate applicable consumable specification is confirmed;<\/li>
      • precision formed components with relatively low spring-load requirements, made to customer drawings.<\/li><\/ul>

        Application boundary:<\/strong> ASTM B863 alone does not make the wire implant grade, aerospace grade or qualified welding filler. Medical, aerospace or filler-wire uses may also require ASTM F67, ISO 5832-2, AMS, AWS, customer 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
