Key Features
High Strength: Offers superior tensile strength, making it suitable for load-bearing applications.
Low Density: Despite its strength, it remains lightweight, which is crucial for both aerospace and medical implants.
Good Ductility: Allows for shaping and forming operations without significant cracking or failure.
Excellent Fatigue Resistance: Important for cyclic loading conditions seen in both aerospace structures and medical devices.
Corrosion Resistance: Excellent in Harsh Environments, resistance to Stress Corrosion Cracking
Biocompatibility: Suitable for Implants, its composition avoids potentially toxic elements like vanadium found in other titanium alloys, enhancing its biocompatibility for medical implants. It is also non-allergenic and less likely to cause adverse reactions in the body, which is critical for long-term implants.
Thermal Stability: It can maintain its mechanical properties at elevated temperatures, a feature useful in aerospace and some medical sterilization processes.
Workability: Can be welded using conventional techniques, which is beneficial for manufacturing complex components or assemblies.
Formability: Its alloying elements allow for better formability than pure titanium, though it requires careful handling to avoid hydrogen pickup.
Packing
Packed in plywood boxes.
