Titanium standard parts

Titanium Standard Parts Grades and Applications

I. Industrial Pure Titanium (TA/GR, lightweight, corrosion-resistant, easy to process)

National Standard (GB/T3620)

• TA1 (GR1): Ti≥99.9%; Low strength, excellent plasticity; Rivets, small screws, non-load-bearing parts, chemical corrosion protection

• TA2 (GR2): Ti≥99.8%; most commonly used pure titanium standard parts; moderate strength, good corrosion resistance; general-purpose bolts, nuts, flanges, seawater/chemical applications.

• TA3 (GR3): Ti≥99.7%; higher strength, slightly lower plasticity; general load-bearing capacity, wear-resistant structural parts.

• TA9 (GR7, Ti-0.2Pd), TA10 (GR12, Ti-0.3Mo-0.8Ni): strong corrosion resistance; fasteners for strong acid/seawater/chloride ion environments and chemical equipment.

II. α+β Titanium Alloys (TC/GR, high strength, heat resistance, mainstream)

National Standard (GB/T3620)

• TC4 (GR5, Ti-6Al-4V): absolute mainstream; tensile strength 895–1030MPa; aerospace/medical/automotive/high-end equipment; full coverage of bolts/studs/nuts.

• TC4 ELI (GR23): Ultra-low clearance (lower C/N/O); medical implants, human implants, high-end medical standard parts

• TC6: Ti-6Al-2.5Mo-1.5Cr; high temperature and high strength (≤500℃); aero-engines, hot-end fasteners

• TC11: Ti-6.5Al-3.5Mo-1.5Zr-0.3Si; good high-temperature creep; aero-engines, high-pressure components

• TC18: Ultra-high strength (≥1100MPa); main load-bearing structures, wings/landing gear, heavy-duty bolts

III. β-Titanium Alloy (TB, ultra-high strength, high elasticity, lightweight)

• TB5 (Ti-15V-3Cr-3Sn-3Al): good cold working, high strength; lightweight aerospace, high-end medical, eyewear/consumer electronics fasteners

• TB6, TB8: Ultra-high strength, fatigue resistance; main load-bearing and heavy-duty structural components for aerospace applications.

IV. Quick Selection Guidelines (Use Directly)

• General Corrosion Resistance/Universal Applications: TA2 (GR2)

• Strong Corrosion/Chemical/Seawater Resistance: TA9 (GR7), TA10 (GR12)

• Aerospace/Aerospace/Heavy-Duty Applications: TC4 (GR5), TC18

• Medical Implants: TC4 ELI (GR23)

• High Temperature/Engine Applications: TC6, TC11

• Lightweight/High Elasticity: TB5
