Titanium Ti-3Al-2.5V Capillary Tube Titanium Gr9 Seamless Tube For Medical And Marine
Description
Ti-3Al-2.5V (Titanium Grade 9, UNS R56320) is an alpha-beta titanium alloy containing aluminium and vanadium. It offers an excellent combination of strength, formability, and corrosion resistance. With a density of 4.43 g/cm³, a melting point of 1625–1675 °C, and a tensile strength of 900–950 MPa, this alloy is well-suited for demanding environments.
Titanium Grade 9 capillary tubing is commonly used in aerospace, medical, and industrial applications where a high strength-to-weight ratio, biocompatibility, and resistance to seawater and chloride corrosion are essential.
