TC4 titanium foil (Ti-6Al-4V, US Standard Grade 5) is an ultra-thin roll of α+β dual-phase titanium alloy, composed of 90% titanium, 6% aluminum, and 4% vanadium. It is the most widely used titanium alloy foil
Key Characteristics
High Specific Strength: Density 4.51 g/cm³ (approximately 60% of steel), tensile strength ≥895 MPa, combining lightweight and high strength.
Excellent Corrosion Resistance: Resistant to seawater, acids, alkalis, and chloride corrosion, superior to stainless steel.
Biocompatibility: Non-toxic, non-allergenic, suitable for human implantation.
Wide Temperature Range: Long-term -250℃~400℃, short-term up to 600℃.
Good Machinability: Can be rolled to ultra-thin 0.01 mm; surface can be mirror-finished/pickled/cold-rolled.
