TC4 Titanium Alloy Coil (Ti-6Al-4V, Grade 5)

Engineered for aerospace, medical, and high-performance industrial applications, TC4 titanium alloy coil delivers unmatched strength-to-weight ratio, fatigue resistance, and corrosion immunity. As the most widely used titanium alloy globally, TC4 (Ti-6Al-4V) combines 6% aluminum and 4% vanadium to achieve 930 MPa tensile strength – 3x stronger than pure titanium – while maintaining 45% lighter weight than steel. Certified to ASTM B863, AMS 4911, and ISO 5832-3, TC4 coil excels in extreme environments, from jet engine components to biomedical implants, with zero corrosion in seawater, chlorides, and acidic media.
