Professional FAQ
Q: What is the main difference between Grade 5 and Grade 2?
A: Grade 5 is an alpha-beta alloy with aluminum and vanadium, offering much higher strength (up to 895 MPa) compared to the commercially pure Grade 2.
Q: Is Grade 5 Titanium biocompatible?
A: Yes, it is widely used for permanent medical implants due to its excellent biocompatibility and high fatigue strength.
Q: How does Shanghai Hangbo ensure the reliability of TC4?
A: Through double or triple VAR melting and 100% ultrasonic testing to eliminate internal defects.
Q: Can Grade 5 be welded?
A: Yes, it is weldable using TIG or laser welding, provided high-purity argon shielding is used to prevent atmospheric contamination.
Q: What are the machining challenges for Grade 5?
A: Its low thermal conductivity requires sharp tools, high coolant flow, and rigid setups to prevent work hardening.
Q: Why choose Shanghai Hangbo for TC4 supply?
A: We provide factory-direct pricing, 100% UT testing, and full traceability for all aerospace-grade materials.
