Titanium Grade 5 (UNS R56400) Seamless Alloy Pipes
6% Aluminum and 4% Vanadium alpha-beta alloy offering the highest strength-to-weight ratio of any commercial piping material.
ASTM B861 Grade 5 / AMS 4942 (Ti-6Al-4V) High-Strength Pipe
Starlight Tubes produces premium Titanium Grade 5 (Ti-6Al-4V / UNS R56400 / DIN 3.7165) seamless alloy pipes and heavy-wall hollow cylinders. Combining high mechanical strength with low density (4.43 g/cm³) and superior fatigue resistance, Grade 5 is the premier material for aerospace hydraulic systems, defense launch tubes, and deepwater offshore drilling risers.
Our Grade 5 pipes undergo vacuum annealing, precision gun-drilling or cold rolling, 100% immersion ultrasonic testing, and complete mechanical certification. Available in annealed or STA condition.
