Tianjin Jingzhou Metal Products provides ASTM Grade 3 Titanium Wire (Chinese grade TA3), the highest strength grade within the commercially pure (CP) titanium series. Engineered for applications that require balanced formability and significantly higher mechanical strength than Grades 1 and 2, TA3 is the premier choice for load-bearing components in medical implants, aerospace auxiliaries, and high-pressure industrial filtration systems.
· Enhanced Strength: Tensile strength of 450–550 MPa, meeting medium-to-high load requirements.
· High Fatigue Resistance: Excellent elasticity and durability for high-frequency vibration environments.
· Industrial Ruggedness: Superior performance in seawater, mining slurry, and harsh chemical media.
· Precision Specs: Diameter range from 0.2 mm to 35.0 mm with a strict +/-0.01mm tolerance.
ASTM Grade 3 Titanium Wire is a medium-to-high strength industrial material that fills the performance gap between standard pure titanium and titanium alloys. While it retains the legendary corrosion resistance of the CP titanium family, its refined chemical composition (higher oxygen content) provides a higher yield strength (≥380 MPa). This makes TA3 indispensable for structural parts where lightweight properties must be combined with mechanical stability. From orthopedic fixation pins to offshore platform fasteners, Grade 3 ensures a long service life under complex working conditions.

FAQ
Q: When should I choose Grade 3 over Grade 2 titanium wire?
A: You should choose Grade 3 when your application requires a higher yield strength and better load-bearing capacity. It is preferred for orthopedic parts and industrial fasteners where Grade 2 might be too soft.
Q: Is Grade 3 still easy to weld?
A: Yes. Although it has higher strength and slightly lower ductility than Grade 2, it still features acceptable weldability and processability for complex structural parts.
Q: Can TA3 be used in aerospace applications?
A: Absolutely. Grade 3 is frequently used for auxiliary aerospace components because of its high fatigue strength and lightweight properties compared to steel.
Q: What surface finishes do you provide for Grade 3 wire?
A: We offer Bright (Polished), pickled, and matte finishes. For medical and precision manufacturing, our bright-polished finish is highly recommended for its smoothness.
