Product Overview
Precision-engineered for mission-critical aerospace systems, this Ti-6Al-4V tube (Grade 5 titanium alloy) meets the stringent requirements of AMS 4944 specification. With an outer diameter of 42.2 mm and wall thickness of 3.5 mm, the tube is supplied in fully annealed condition to ensure optimal ductility, microstructural homogeneity, and stress-relieved dimensional stability. Each lot undergoes comprehensive non-destructive testing (NDT), including ultrasonic (UT) and eddy current (ET) inspection per ASTM E213/E243, guaranteeing zero internal discontinuities and surface integrity — essential for aerospace metal tube applications where reliability is non-negotiable. As a high-performance titanium alloy tube, it delivers exceptional strength-to-density ratio, outstanding corrosion resistance in aggressive environments (e.g., salt spray, jet fuel, hydraulic fluids), and superior creep resistance at elevated temperatures up to 400°C.

Applications
This NDT tested titanium pipe is widely deployed across civil and military aerospace platforms — including airframe hydraulic lines, engine bleed air ducts, landing gear actuators, and UAV structural tubing. Its combination of lightweight performance, fatigue resilience, and compatibility with high-temperature sealing systems makes it ideal for next-generation aircraft, satellite propulsion manifolds, and hypersonic vehicle thermal management systems. Also specified in high-reliability defense electronics cooling channels and medical implant device delivery systems requiring biocompatible, ultra-clean tubing.
